LeetCode 761: Special Binary String — Recursive Decomposition & Custom Sort Proof

This article analyzes LeetCode 761 Special Binary String, proving that valid strings decompose into minimal '1...0' units, then achieves maximum lexicographical order through recursive substring sorting and a custom comparator proven to satisfy total order properties (completeness, antisymmetry, transitivity), with Java, C++, and TypeScript implementations.
