Leetcode 723. Candy Crush

Given an m×n board of integer "candies," repeatedly find and remove any horizontal or vertical runs of ≥3 identical candies, let the remaining candies fall down to fill gaps (gravity), and repeat until no more removals are possible — return the stabilized board. This tests grid scanning and iterative simulation to detect runs and collapse columns to a fixed point.
