Consider our authentication protocol 4.0, in which Alice authenticates herself to Bob, which we saw works well (i.e., we found no flaws in it.). Now suppose that at the same time that Alice authenticates herself to Bob, Bob must authenticate himself to Alice. Give a scenario by which Trudy, pretending to be Alice, can now authenticate herself to Bob as Alice.

Answers

According to protocol 4.0, the scenario can be defined in terms of Bob, Alice and Trudy as follows:

The communication is done between Bob and Alice only in whom they share a secret key KAB with each other. The Trudy is an intruder who wants to get the information that is being communicated between Alice and Bob. To do so, Trudy wants Bob to initiate the communication by authenticating herself her Alice. Thus, Trudy waits for the Bob to start in-order to make the Bob authenticate himself.

Here are the steps how the communication is done between the Bob and Trudy:

Step 1: Bob starts the communication by himself to other side and waits for the reply.

Step 2: Trudy starts to disguise as Alice herself and authenticate herself to Bob.

Step 3: After looking at the reply, Bob sends the nonce key to Trudy. At this step, still Trudy does not know the KAB(R) in-order to reply to Bob.

Step 4: At this point Trudy response to the step-1 while Bob still continuing to authentication. Trudy picks the nonce for the Bob to encrypt the message with the Bob sent nonce in the Step-3.

Step 5: Now Bob completes his own authentication to himself on the other side of encrypting the nonce he sent at step 4. Where, Trudy gets the nonce key KAB( R).

Step 6: Now, Trudy completes her authentication in responding to R that is sent by Bob in step 3. At this point, Trudy has responded properly, so Bob thinks that he is communicating with Alice(Trudy).

The actual scenario with respect to above steps, the communication is done as follows:

Bob: “I am Bob”

Trudy: “I am Alice”

Bob: “R”

Trudy: “R”

Bob: “KAB (R )” – Bob completes his authentication.

Trudy: Get the KAB (R ) – Trudy complete her authentication.

Thus, the communication is started between the Bob and Trudy instead of Bob and Alice according to protocol 4.0.

Depends on where you’re from and what grading scale is used. I wouldn’t say you’re ruined if you push hard the rest of the year.

You are given an array of integers. Your task is to create pairs of them, such that every created pair has the same sum. This sum is not specified, but the number of created pairs should be the maximum possible. Each array element may belong to one pair only.

Write a function

class Solution public int
solution (int[] A); }

that, given an array A consisting of N integers, returns the maximum possible number of pairs with the same sum.

Examples:
1. Given A = [1, 9, 8, 100, 2], the function should return 2. The pairs are (A[0]. A[1]) and (A[2], A[4]); the sum of each pair is 10.
2. Given A = [2, 2, 2, 3], the function should return 1. Although, for instance, A[0]+A[1] = A[0]+A[2], the pairs (A[0], A[1]) and (A[0], A[2]) cannot exist at the same time, because they both contain a common element, A[0].

for j in range(i+1,len(nums)):

# calculate the sum of current 2 elements

sum = nums[i] + nums[j]

# if the sum is already in the dictionay

if sum in sumAndpair:

# check if the current index have already been used

# if yes, then continue to next iteration

# this will make sure that same number have not been used more than once

if i in sumAndpair[sum] or j in sumAndpair[sum]:

continue

# if no, then append the current i and j to the value of current sum

else:

sumAndpair[sum].append(i)

sumAndpair[sum].append(j)

# if the current sum is not in the dictionary

# add the sum as key with a list of index used

else:

sumAndpair[sum] = [i, j]

# copmpute the maximum possible number of pairs with the same sum

how to count binary ? Help Better understand this question

Answers

Explanation:

For each row in the picture, you have to switch on some of the bits to create the number on the left.

Each bit has a value, a "weight" so to speak. By switching on the bit, you add that weight to the sum.

These "weights" are shown at the top row.

So to create 4, it's easy, you just switch on the '4' bit.

Same for 128, only one bit has to be switched on.

40 is a bit more involved, now you have to switch on 32 and 8, since 32+8 is 40.

For every number, there is exactly one combination of switched on bits to create that number. In the case of 40, the binary representation is:

C. s1.equals(s2) && !s1.equalsIgnoreCase(s2)
D. !s1.equals(s2) && !s1.equalsIgnoreCase(s2)

Answers

Answer:

B, C, B

Explanation:

According to my understanding of these questions, these are in Java.

For the first one, there is a built in function called .length() for a string, so it's answer B.

For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.

The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.
