blockchain Interview Questions

This Coinbase interview question explores a variation of the classical knapsack problem applied to cryptocurrency ledger management, where you must select a subset of pending ledger entries to maximize total transaction fees within a strict weight constraint. The challenge evaluates your ability to apply a density-based heuristic strategy rather than exact dynamic programming to efficiently prioritize high-value payloads under capacity limits.
