1. Bob received a mail from some unknown person. This mail was having a link to some blogging
website which contains free CS/IT and other study materials. Which of the following attacks can
occur when a malicious user convinces a victim (in this case Bob) to send a request to a server
with malicious input and the server echoes the input back to client?
Oa. Reflected XSS
Ob. Persistent XSS
Oc. Insecure direct object references
Od. Failure to restrict URL access
e. NA
2. Which of the following is most likely to result from invalidated redirects and forwards?
Oa. Brute force attack
Ob. Network sniffing
Oc. Man-in-the-middle attack
Od. Bypassed authorization checks
e. NA
Answers
The request to the server that echoes can be sent as the input through the Reflected XSS. Bypassed authorization checks occur from unvalidated redirects and forwards. Thus, options a and d are correct.
What is Reflected XSS?Reflected XSS is an attack that occurs as cross-site and takes place by the intervention of the malicious and suspicious injections of the contents through the links sent by the emails.
The suspicious link when clicked causes the attack of the viruses on the user's system. The link convinces the user to send a request to the server containing malicious and unsafe content.
The invalid malicious forwards and redirects result in the bypassed authorization checks. The scanners of the applications are not able to differentiate between the safe and the harmful content and lose the ability to access the right and the wrong.

What happens when a string doesn’t include the separator that’s specified in the parameter of the split() method?
Answers
Answer:
Nothing
Explanation:
If a seperator value is provided as an argument within the split() method and the string does not include that value then the string will remain the same and will not be split. If no value is provided as an argument within the split() method, then the string that the method is being applied to will automatically be split in every space character (" ") that exists within it. This is the default value of split() when no argument is passed to it.
Translate each statement into a logical expression. Then negate the expression by adding a negation operation to the beginning of the expression. Apply De Morgan's law until each negation operation applies directly to a predicate and then translate the logical expression back into English.
Sample question: Some patient was given the placebo and the medication.
∃x (P(x) ∧ D(x))
Negation: ¬∃x (P(x) ∧ D(x))
Applying De Morgan's law: ∀x (¬P(x) ∨ ¬D(x))
English: Every patient was either not given the placebo or not given the medication (or both).
(a) Every patient was given the medication.
(b) Every patient was given the medication or the placebo or both.
(c) There is a patient who took the medication and had migraines.
(d) Every patient who took the placebo had migraines. (Hint: you will need to apply the conditional identity, p → q ≡ ¬p ∨ q.)
Answers
Answer:
P(x): x was given the placebo
D(x): x was given the medication
M(x): x had migraines
Explanation:
(a) Every patient was given the medication
Solution:
∀x D(x)
∀ represents for all and here it represents Every patient. D(x) represents x was given the medication.
Negation: ¬∀x D(x).
This is the negation of Every patient was given the medication.
The basic formula for De- Morgan's Law in predicate logic is:
¬(P∨Q)⇔(¬P∧¬Q)
¬(P∧Q)⇔(¬P∨¬Q)
Applying De Morgan's Law:
∃x ¬D(x)
∃ represents there exists some. As D(x) represents x was given the medication so negation of D(x) which is ¬D(x) shows x was not given medication. So there exists some patient who was not given the medication.
Logical expression back into English:
There was a patient who was not given the medication.
(b) Every patient was given the medication or the placebo or both.
Solution:
∀x (D(x) ∨ P(x))
∀ represents for all and here it represents Every patient. D(x) represents x was given the medication. P(x) represents x was given the placebo . V represents Or which shows that every patient was given medication or placebo or both.
Negation: ¬∀x (D(x) ∨ P(x))
This is the negation or false statement of Every patient was given the medication or the placebo or both.
Applying De Morgan's Law:
∃x (¬D(x) ∧ ¬P(x))
∃ represents there exists some. As D(x) represents x was given the medication so negation of D(x) which is ¬D(x) shows x was not given medication. As P(x) represents x was given the placebo so negation of P(x) which is ¬P(x) shows x was not given placebo. So there exists some patient who was neither given medication nor placebo.
Logical expression back into English:
There was a patient who was neither given the medication nor the placebo.
(c) There is a patient who took the medication and had migraines.
Solution:
∃x (D(x) ∧ M(x))
∃ represents there exists some. D(x) represents x was given the medication. M(x) represents x had migraines. ∧ represents and which means patient took medication AND had migraines. So the above logical expression means there exists a patient who took medication and had migraines..
Negation:
¬∃x (D(x) ∧ M(x))
This is the negation or false part of the above logical expression: There is a patient who took the medication and had migraines.
Applying De Morgan's Laws:
∀x (¬D(x) ∨ ¬M(x))
∀ represents for all. As D(x) represents x was given the medication so negation of D(x) which is ¬D(x) shows x was not given medication. As M(x) represents x had migraines so negation of ¬M(x) shows x did not have migraines. ∨ represents that patient was not given medication or had migraines or both.
Logical expression back into English:
Every patient was not given the medication or did not have migraines or both.
(d) Every patient who took the placebo had migraines.
Solution:
∀x (P(x) → M(x))
∀ means for all. P(x) represents x was given the placebo . M(x) represents x had migraines. So the above logical expressions represents that every patient who took the placebo had migraines.
Here we are using conditional identity which is defined as follows:
Conditional identity, p → q ≡ ¬p ∨ q.
Negation:
¬∀x (P(x) → M(x))
¬∀ means not all. P(x) implies M(x). The above expression is the negation of Every patient who took the placebo had migraines. So this negation means that Not every patient who took placebo had migraines.
Applying De Morgan's Law:
∃x (P(x) ∧ ¬M(x))
∃ represents there exists some. P(x) represents x was given the placebo . ¬M(x) represents x did not have migraines. So there exists a patient who was given placebo and that patient did not have migraine.
Logical expression back into English:
There is a patient who was given the placebo and did not have migraines.

When creating a website, it is important to create a sitemap so that a search engine can find, crawl and index all of your website's content. a sitemap makes site creation much more efficient and simple. A sitemap also helps site developers (assuming you have any) understand the layout of your website, so that they can design according to your needs.
A wireframe is another important step in the web design process. Creating a website is like building a house. To build the house, you first need a foundation on which to build it upon. Without that foundation, the house will collapse. The same goes for a website. If you create a wireframe as a rough draft of your website before going through and adding final touches, the entire design process will become much easier. If you do not first create a wireframe, the design process will be considerably more difficult, and you are more likely to encounter problems later on.
To me, the wireframe is the most important due to the fact that is necessary in order to create a good website. In order to create a sitemap, you first need a rough outline of your website. Without that outline, creating a sitemap is impossible.

A - m is almost equal to M
B - m is very small
Answers
B - If m is very small, then the trees in the random forest will have high variance and low bias. This is because each tree will be trained on a small subset of features, and will therefore be more sensitive to noise in the data.

Answers
Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
#include <iostream>

A sequential circuit has one flip-flop Q, two inputs X and Y, and one output S. The circuit consists of a D flip-flop with S as its output and logic implementing the function D = X ⊕ Y ⊕ S with D as the input to the D flip-flop. Derive the state table and state dia- gram of the sequential circuit.
Answers
To derive the state table and state diagram of the sequential circuit, we first need to determine the possible states of the flip-flop Q, and the next states based on the input values X and Y and the current state of Q.
The state table for the sequential circuit would look like this:
Q(t) X Y Q(t+1) S
0 0 0 0 0
0 0 1 1 1
0 1 0 1 1
0 1 1 0 0
1 0 0 1 1
1 0 1 0 0
1 1 0 0 0
1 1 1 1 1
The state diagram for the sequential circuit would look like this:
S=0 S=1

What is flip-flop Q?
A flip-flop is a circuit that is used to store binary data in digital electronic systems. It is a type of latch circuit that is used as a memory element in digital logic circuits. Flip-flops can be either positive edge-triggered or negative edge-triggered, and can be either level-sensitive or edge-sensitive. The most common types of flip-flops are SR flip-flops, JK flip-flops and D flip-flops.
In this case, Q is a flip-flop that is used as a memory element in the sequential circuit. It stores the current state of the circuit and is used in the logic implementation of the circuit's function. The output of this flip-flop is used as an input to the next state of the circuit, and it's also the output of the circuit.
