Leetcode 1985. Find the Kth Largest Integer in the Array

Given an array of non‑negative integers encoded as decimal strings (no leading zeros) and an integer k, return the k-th largest numeric value treating duplicates as distinct. The core challenge is comparing potentially long numeric strings efficiently (compare by length then lexicographically) and selecting the k-th largest (via sorting, heap, or selection).

Leetcode 286. Walls and Gates

Given a 2D grid of empty rooms (INF), walls (-1), and gates (0), fill each empty room with the distance to its nearest gate (leave walls and gates unchanged). This is a multi-source shortest-path problem on a grid that is typically solved by running a BFS from all gates simultaneously to compute minimum distances in O(mn) time.
