a method of collecting data tell me if  i'm wrong or right plz

Explanation:

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].

def solution(nums):

# form a dictionary which will store

sumAndpair = {}

# for every element in list nums

for i in range(len(nums)):

# iterate on all the element to the right of current element

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

# which will be the maximum length value out of all the possible sum

# this maximum length will be divided by 2, since a pair of i, j contrinute to one sum

why do you think mobile devices have CPUs that are less powerful than those in a larger desktop computer?

Answers

Mobile CPUs are found in laptops and are often slower than their desktop counterparts because they have to be more power-efficient and generate less heat. High power consumption and high heat generation can be a problem for a battery-powered laptop with a relatively small chassis

Mobile devices have CPUs that are less powerful than those in a larger desktop computer needs power as well as the device memory that was needed is not present.

What is CPU?

A sample member of the list data is a1 = ['male', True] where the second item is True if the person is on the phone.

for item in data:
if item[0] == 'male':
males = males + 1
if item[___
]:
malesOnPhone = malesOnPhone + 1
Choices are 1, 2, 3. Answer is for if item[___]:

Answers

Answer:

0

Explanation:
In the lists, indexation starts from 0, because of that in if statement we compare item[0] which is 'male' and 'male', and then males is itterated within for loop.

Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.

What loop for sample member of the list data?

An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.

FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.

Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.

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.
