Topic Strategy: Bitwise Operations Programs
This topic is best practiced through repetition with variation. Solve each program, then modify constraints and test alternate approaches so you understand why one solution performs better than another.
During interviews, explain the approach before coding: input assumptions, core logic, complexity, and edge cases. Clear reasoning often matters as much as final code correctness.
Once comfortable, time-box each question and target clean, readable code with meaningful variable names and a quick dry run explanation.
