# Hackerearth Maximize the sum problem solution

In this HackerEarth Maximize the sum problem solution You are given an array A of N integers. You want to choose some integers from the array subject to the condition that the number of distinct integers chosen should not exceed K. Your task is to maximize the sum of chosen numbers. You are given T test cases.
