Count all distinct pairs with difference equal to k

#include #include using namespace std; void printArray(int a[], int len) { for(int i=0;i k) l++; } cout << "count =" << count; } int main() { // your code goes here int a[] = {8, 12, 16, 4, 0, 20}; cout << "array - "; printArray(a, sizeof(a)/sizeof(a[0])); countPairsWithDiffK(a, sizeof(a)/sizeof(a[0]), 4); return 0; }
