When implementing iterative algorithms, ensure comprehensive handling of edge cases and boundary conditions. This includes: 1. Using while loops instead of if-else chains for repetitive operations 2. Explicitly handling overflow/underflow scenarios 3. Validating both start and end conditions 4. Testing with boundary values Example - Before (problematic): ```zig if (strings.endsWith(normalized_name, "/")) { normalized_name = normalized_name[0 .. normalized_name.len - 1]; } else if (strings.endsWith(normalized_name, "\\")) { normalized_name = normalized_name[0 .. normalized_name.len - 1]; } ``` Example - After (robust): ```zig while (strings.endsWith(normalized_name, "/") or strings.endsWith(normalized_name, "\\")) { normalized_name = normalized_name[0 .. normalized_name.len - 1]; } ``` This approach prevents issues like: - Missed cases in chained conditions - Integer overflow/underflow in calculations - Incomplete processing of repeated patterns - Boundary condition errors When implementing iterative algorithms, always consider: 1. What happens at zero/empty input? 2. What happens at maximum values? 3. Can the operation need to be repeated? 4. Are all edge cases handled explicitly?
