Solution

The problem is asking to calculate the combination of N items taken R at a time. This is often represented as "N choose R" or NCR.

The formula for NCR is N! / [R!(N-R)!] where "!" denotes factorial, which is the product of all positive integers up to that number.

Here are the steps to solve the problem:

  1. Read the input values of N and R.

  2. Calculate the factorial of N. This can be done using a loop that multiplies all integers from 1 to N.

  3. Calculate the factorial of

You are given two integers 'n' and 'r' and a prime number 'p'. Your task is to find (nCr) % p where nCr can be calculated as n! / (r! * (n - r)!).Note :N! = 1 * 2 * 3 *... NInput format :The first line of input contains a single integer 'T', representing the number of test cases. The first line of each test case contains three space-separated integers 'n', 'r', and 'p'.Output format :For each test case, print a single line containing an integer representing the value of (nCr) % p.The output of each test case will be printed on a separate line.Note:You don't need to input or print anything, it has already been taken care of. Just implement the given function.Constraints :1 <= T <= 5 1 <= n, r, p <= 5 * 10 ^ 2p is prime number.Time limit: 1 sec.Sample Input 1 :2 5 2 114 3 13Sample Output 1 :104Explanation for Sample Output 1:In test case 1, n = 5, r = 2, and p = 11n C r = 5 C 2 = (5 * 4) / (2!) = 10n C r % p = 10 % 11 = 10. So the answer will be 10.In test case 2,n = 4, r = 3, and p = 13 n C r = 4 C 3 = 4 C 1 = 4 n C r % p = 4 % 13 = 4. So the answer will be 4.Sample Input 2 :25 2 1710 2 13Sample Output 2 :106
