January 2025 performance summary for hayati01/CodingTasksB37GR3. Key feature delivered: String Unique Characters Extraction Utility in Java. The method iterates through the input string, identifies characters that appear only once by comparing first and last occurrences, and returns those unique characters as a new string. This creates a reusable string-processing utility that supports downstream data parsing, validation, and other tasks requiring character-level uniqueness. Commit 88d09dfc17c407cd04a1322b6bdef6eaa3439b9f implements the FindUniqueChars_W7 task solution.

Concise monthly summary for December 2024 focused on delivering a practical, teachable Java example and demonstrating solid code delivery in a single repository. Feature work was scoped to a clear demonstration of an algorithmic technique with immediate educational value and minimal maintenance footprint.

November 2024 performance summary for hayati01/CodingTasksB37GR3. Delivered two core features with a focus on testability and maintainable API surfaces. OddOrEven Parity Utility: created an OddOrEven class with parity checking and refactored from a placeholder main-driven prototype to a reusable API exposing identify(int) -> 'Even'|'Odd'. Main method removed to enable straightforward unit testing and easier integration. FINRA Number Replacer (1-30): implemented a Java program that prints numbers 1 through 30 with a specific substitution for numbers divisible by both 3 and 5, emitting 'FINRA' for those cases and keeping simple iteration logic for maintainability.
