Median of Two Sorted Arrays - LeetCode 4 - Python - Visually Explained
LeetCode #4 — one of the hardest interview problems. We explore why brute-force merge and two pointers both fall short at O(m+n), then reveal the real trick: binary search on the shorter array to find the perfect cut position. Full visual walkthrough with a concrete example, plus clean Python code. Time O(log(min(m,n))), Space O(1).
