Punish the Students

PROBLEM :

A Professor conducts a Computer Science paper for all students. He had strictly ordered all students to sit according to their roll numbers. However when he started checking the papers, he found out that all the papers were randomly ordered. The students had sat randomly during the exam instead of sitting according to their roll numbers. Professor was very angry and he wanted to teach the students a lesson. He decides to sort the papers by Bubble Sort, count the number of swaps required for each and every student and deduct as many marks of a student as were the number of swaps required for that student. However he also has to maintain a class average of atleast M else he may lose his job. The Professor wants to know whether he should punish the students or save his job.

Input:

The first line of input takes an integer T denoting the total number of test cases. Then T test cases follow. Each test case has 3 input lines.

The first line of each test case takes the number of students, N and the minimum average to be maintained,M.

The second line of each test case takes N space separated integers, the ith integer denoting the roll number of the student sitting in i th seat during exam.

The third line of each test case takes N space separated integer, the i th integer denoting the marks obtained by the student having roll number i.

Output:

Print 1 if he can teach the students a lesson without putting his job at risk, else print 0.

Constraints:

1<=T<=100
1<=N<=1000
1<=M<=100
1<=Marks<=100

Example:

Input:
2
5 68
3 2 4 1 5
50 67 89 79 58
6 67.5
5 4 1 3 2 6
78 98 86 67 78 79

Output:
0
1

Explanation:

Test Case#1

Iteration

     1                         2 3 1 4 5                  -                       Array

                                1 1 1 1 0                  -                      Swaps

     2                         2 1 3 4 5                   -                       Array

                                1 2 2 1 0                   -                      Swaps

     3                         1 2 3 4 5                    -                       Array

                                3 2 2 1 0                   -                      Swaps


Marks of 1st student = 50 - 3 = 47

Marks of 2nd student = 67 - 2 = 65

Marks of 3rd student = 89 - 2 = 87

Marks of 4th student = 79 - 1 = 78

Marks of 5th student = 58 - 0 = 58

Class Average = 67<68

Hence, Professor decides to save his job and O/P is 0.

The remaining test cases follow from the same logic.

Count ways to N'th Stair(Order does not matter)

PROBLEM : There are n stairs, a person standing at the bottom wants to reach the top. The person can climb either 1 stair or 2 stairs at a time. Count the number of ways, the person can reach the top (order does not matter). Order does not matter means for n=4 {1 2 1},{2 1 1},{1 1 2} are considered same. Input: The first line contains an integer 'T' denoting the total number of test cases. In each test cases, an integer N will be given. Output: Print number of possible ways to reach Nth stair. Constraints: 1<=T<=1000 1<=N<=100 Example: Input: 1 4 Output: 3 -------------------------------------------------------------------------------- SIMPLE c++ IMPLEMENTATION : -------------------------------------------------------------------------------- #include<iostream> using namespace std; long long Count_nth_stair(long long ) ; int main()  { int t ; long long no ; cin>>t ; while(t--) {    cin>>no ; ...

Primality Test ( CodeChef Problem code: PRB01 )

PROBLEM : Alice and Bob are meeting after a long time. As usual they love to play some math games. This times Alice takes the call and decides the game. The game is very simple, Alice says out an integer and Bob has to say whether the number is prime or not. Bob as usual knows the logic but since Alice doesn't give Bob much time to think, so Bob decides to write a computer program. Help Bob accomplish this task by writing a computer program which will calculate whether the number is prime or not . Input The first line of the input contains T testcases, T lines follow Each of T line contains an integer N which has to be tested for primality Output For each test case output in a separate line, "yes" if the number is prime else "no" Constraints 1<=T<=20 1<=N<=10000 1<=M<=10000 Input: 5 23 13 20 1000 99991 Output: yes yes no no yes       --------------------------------------------------------------------------...
