Minimum window subsequence

CodingAlgorithms & data structuresSenior–Staff~35 min

Given strings s and t, return the minimum (contiguous) substring w of s such that t is a SUBSEQUENCE of w. If there is no such window, return the empty string. If multiple minimum-length windows exist, return the one with the left-most starting index. 1 <= len(s) <= 2*10^4, 1 <= len(t) <= 100.

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
