Developed and contributed a new Parity Bit System Exercise to the exercism/problem-specifications repository, focusing on parity-based error detection for intergalactic data transmission scenarios. The work involved designing a problem specification that enforces even parity across 8-bit data segments, with explicit logic for calculating and inserting parity bits in both complete and incomplete data blocks. Emphasized clear algorithmic descriptions and robust edge-case handling to strengthen learners’ understanding of data integrity concepts. Utilized skills in problem specification design, algorithm documentation, and disciplined Git workflows. All changes were reviewed and integrated following standard code review and CI processes, with no bugs reported.
