Logic:- Logic is very simple we have to take a number and compare is the first number is less than the second number then first number + second number divide by number input from user If the sum is divisible by number than increase the count or else for condition do not increase a count variable. See the explanation section with an example.

Explanation:- Let's take an example and with the help of an example try to understand the problem divisible pairs sum. Taking an input from the user and check if the number has divisible pairs sum or not.

User Input:- 6 is a size of an array and number 3 is for divide the pair sum.

6 3
1 3 2 6 1 2

So check the following conditions with all condition, here condition 1 is that first number should be less than the second number.

1 + 3 = 3
1 + 2 = 3
3 + 6 = 9
2 + 1 = 3
1 + 2 = 3

Only all above 5 conditions is true for given input and if we divide the sum pair than no reminder is occurring. Hence we get our answer, the answer is 5.

Solution:-

#include <bits/stdc++.h>
using namespace std;

int main()
{

int i, j ,k ,n, count=0;

cin >> n >> k;

vector<int> array(n);

for(i = 0; i < n ; i++)
{
cin >> array[i];
}

for(i = 0; i < n ; i++)
{
for(j = 0; j < n ; j++)
{
if(i < j)
{
if((array[i] + array[j]) % k == 0)
count++;
}
}
}
cout<<count;
