AnswersQuestion : Given a set of N numbers [1,N], partition them into 2 disjoint subsets based on a set of K queries.

- robb.krakow July 25, 2018 in United States

Input:

Input:

N = 4

K = [(1, 2), (1, 3), (2, 4)]

AnswerGiven two arrays. One is for tasks (Processes) and each element depicts the amount of cores required to run the task. 2nd array is an array of CPU where each element depicts the no of cores in it.We have to tell how many maximum number of tasks can be allocated. Example: Task: [3, 5, 7], Cores: [1, 3, 5] . Here only task 0 and 1 can be allocated to CPU 1 and 2 . So, answer=2.

AnswerWe are given a list of N integers and another positive integer K. We need to compute the number of ways in which the product P of the

- sowjanyanani16 July 22, 2018 in United States

given N integers can be expressed as a product of K positive integers (not

necessarily distinct). The order of the factors in the expression is not

important. For example, 1 x 2 x 3 and 2 x 3 x 1 are not counted as different

ways of expressing 6 as a product of three integers.

Input Format

The first line contains two space-separated integers, N and K

The next line contains N-space separated integers

Output

One line containing the number of ways in which the product of the N

integers can be expressed as a product of K positive integers

Example:

Input

2 3

4 16

Output

7

Explanation

The product is 64. This can be expressed as a product of three integers in

the following ways:

1 x 1 x 64

1 x 2 x 32

1 x 4 x 16

1 x 8 x 8

2 x 2 x 16

2 x 4 x 8

AnswersFriend circle:

- Jaideep July 21, 2018 in India

There are N students in a class. Some of them are friends, while some are not. Their friendship is transitive in nature. For example, if A is a direct friend of B, and B is a direct friend of C, then A is an indirect friend of C. And we defined a friend circle is a group of students who are direct or indirect friends.

Given a N*N matrix M representing the friend relationship between students in the class. If M[i][j] = 1, then the ith and jth students are direct friends with each other, otherwise not. And you have to output the total number of friend circles among all the students.

Input:

[[1,1,0],

[1,1,0],

[0,0,1]]

Output: 2

Explanation:The 0th and 1st students are direct friends, so they are in a friend circle.

The 2nd student himself is in a friend circle. So return 2.

Input:

[[1,1,0],

[1,1,1],

[0,1,1]]

Output: 1

Explanation:The 0th and 1st students are direct friends, the 1st and 2nd students are direct friends,

so the 0th and 2nd students are indirect friends. All of them are in the same friend circle, so return 1.| Report Duplicate | Flag | PURGE

AnswersUniversal Lucky string:

- Jaideep July 21, 2018 in India

All characters in S have the same exact frequency (i.e., occur the same number of times). For example, "aabbcc" is valid, but "baacddd" is not valid.

2. Deleting exactly 1 character from S will result in all its characters having the same frequency. For example, "aabbccc" and "aabbc" are valid because all their letters will have the same frequency if we remove occurrence of "c", but "aabbcccc" is not valid because we'd need to remove 2 characters.| Report Duplicate | Flag | PURGE

Answer**Game of Bits**

- harshit.knit July 19, 2018 in India

Yale and Xavier are playing a game with numbers. Each round of the game starts with a number given to them by Zita, Yale’s little sister.

The number n is expressed as a binary integer with p bits

For every round, Xavier gets the first move.

The game came consists of moves performed by Yale and Xavier alternately.

The mth move of the game involves performing these operations on the number:

Toggling the mth bit (numbering of bits starts from left) of the number.

Toggling the left adjacent bit of m (if such a bit exists) if it is equal to the mth bit before toggling in step 1; otherwise keep it as is.

Toggling the right adjacent bit of m (if such a bit exists) if it is equal to the mth bit before toggling in step 1; otherwise keep it as is.

This modification of the number goes on until all p moves are made. If the modified number (as a result of all the operations) is

equal (or a distance one away) from the original number, then the person who made the last move wins the round; otherwise the other one wins the round.

**Note:**

The number given to them is converted to its binary form and represented with the help of minimum number of bits.

The numbering for the bits starts from the leftmost bit.

**Constraints**

1<=r<=10^6

1<=n<=10^6, where n is the number given by Zita in any round

**Input Format**

The first line contains a number, r, denoting the number of rounds in the game.

This is followed by r lines, where the ith line contains the number given by Zita for the ith round.

**Output Format**

The output of the problem has r lines, where the ith line contains the winner of ith round as X if Xavier wins ith round or Y if Yale wins the ith round.

**Sample Input**

1

11

**Sample Output**

Y

**Explanation**

11 is represented as 1011 using minimum number of bits in binary.

When Xavier makes the first move, it becomes 0011.

Then Yale makes the 2nd move and it becomes 1111.

After the third move made by Xavier, it becomes 1000.

After the last move by Yale, it becomes 1011 which is 11 in decimal.

The last move was made Yale and the modified number is equal or adjacent to 11,

therefore, Yale wins this round.| Report Duplicate | Flag | PURGE

AnswerI want to implement a simple HTTP Denial-of-Service protection. There are clients that can send HTTP request to a Server (i.e. a GET Method of http://10.1.1.2:8080/?clientId=7)

- Patrick July 18, 2018 in United States

if in an interval of 10 seconds more then 10 request comes from a specific client the 11th, 12th.. requests will get blocked. until 10 seconds from the first request will pass and then a new time windows of 10 seconds will be open. the idea is no more than 10 requests per 10 secs.

The time frame starts on each client’s first request and ends 10 seconds later.

I want to implement this logic on the server. Which data structures/collection/custom made object would you build to implement such a logic...

it is also important to have a threats safe solution.. and performances is also a factor here..
