WebBecause, if at a particular bit we have 0 1s or 1 1s, there is no problem, xor will cover that part of sum. When there are 2 1s in a particular bit, then xor will make it 0, so we need to add 2 ∗ a n d ( a, b) for places that have bit in both a and b, similarly other cases. Now, we see places where a, b and c all have bit set. Web2 Mar 2024 · Given an array arr [] of size n, we need to find the sum of all the values that come from XORing all the elements of the subsets.
