From 5947d989ca80e9d8db3a20784fd5b908a35c6d98 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 11 May 2026 02:01:28 +0000 Subject: [PATCH] Standardize repository structure and improve documentation - Rename directories 'Error-debug' to 'ErrorHandling' and 'deque' to 'Deque' for consistency. - Rename several Python scripts in 'Arrays/' and 'Trees/' to follow PascalCase. - Update root 'README.md' with new file links, corrected Table of Contents anchors, and updated Shell Sort complexity. - Update subdirectory 'README.md' files with correct links and complexity analysis in LaTeX. - Verify that all 50 Python scripts are correctly referenced and functional.
