Debug Utilities

Compare solution outputs, validate array sizes, locate spacing errors, and estimate memories.

Compare expected output with received outputs line by line, ignoring trailing newlines.

Check differences line by line to see correct, missing, extra, or modified lines.

Find the exact line, column, and ASCII code of the first mismatching character.

Verify multiset element counts by comparing occurrence frequencies.

Check array sorting bounds (ascending, descending, strict, non-strict) and locate breaks.

Scan elements list to locate duplicate values, counts, and their index offsets.

Randomize array elements with deterministic seed configurations.

Verify output spacing layout to avoid presentation errors or mixed tab indentation bugs.

Validate N-sized arrays and matrices against constraints limits.

Run manual comparison test runs comparing brute force outputs against optimized solvers.

Estimate heap memory footprint of standard C++ container variables.
