WebMay 31, 2024 · General Approach. Firstly, we need to generate all the possible subsets from the input array. Then, for all calculated subsets, calculate the XOR of all elements in … WebNov 20, 2024 · Solution. We can easily solve this problem for any subset length N using branch-and-bound. Branch-and-bound can be either implemented iteratively (e.g., using depth-first search and a stack) or recursively. I opted for the recursive approach as it is more concise and easier to reason about (in my opinion, at least). cycloplegics and mydriatics https://simul-fortes.com
