USACO US Open 2025 Silver Problem 1 - Sequence Construction - Solution

Here I am going to present the solution for the first problem from the US Open 2025 USACO Silver Contest, a problem where we can start from a simple construction made of numbers equal to powers of two - 1 and after deducing some extra casework, we can solve all the possible cases depending on parity of m and k.
