If we will notice then it is obvious in actual we are partitioning the sum of elements of the given array in two parts (number of elements does not matter in subsets). i.e [1 , 5 , 11 , 5] , sum of each element of array/list will be 22. Now we will look for subsets that have the sum equal to (sum of each element of the array)/2 i.e, (22/2 = 11).Your task is to check if there exists a subset in 'ARR' with a sum equal to 'K'. Note: Return true if there exists a subset with sum equal to 'K'. Otherwise, return false. For Example : If 'ARR' is {1,2,3,4} and 'K' = 4, then there exists 2 subsets with sum = 4. These are {1,3} and {4}. Hence, return true. Input Format :You are given an array of 'N' integers, and a positive integer 'K'. You need to determine if it is possible to divide the array into 'K' non-empty subsets such that the sum of elements of each subset is equal. Note: 1. The array can have duplicate elements. 2. Each of the array elements must belong to exactly one of the 'K' subsets. 3.The Partition to K Equal Sum Subsets LeetCode Solution - "Partition to K Equal Sum Subsets" states that you're given the integer array nums and an integer k, return true if it is possible to have k non-empty subsets whose sums are all equal.
