URL: https://usaco.guide/problems/cf-1556D/user-solutions Module: Problem Solution - Take a Guess (ID: cf-1556D) Topic: Suggestion Message: I believe there's an easier way to calculate A + B, since we have A + B = A AND B + A OR B, we don't have to calculate A XOR B. The equation is also more useful than the one mentioned in the solution.
