The runtime of this solution is O(2^n). This enumeration algorithm is similar with the problemSubsets. The difference is that Subsets has to get all possible subsets. But this problem can terminate the check earlier if for one element arr[startIdx] including it in the subset and not inclu...
: Here, we are going to learn to make partitions for k subsets each of them having equal sum using backtracking. Description This is a standard interview problem to make partitions forksubsets each of them having equal sum using backtracking. Problem statement A set is given. You have to mak...
