Subsequence check

CodingAlgorithms & data structuresEntry–Mid~15 min

Return whether the first string is a subsequence of the second (characters in order, not necessarily contiguous).

Implement
is_subsequence(s: str, t: str) → bool
Examples
in["abc","ahbgdc"]outtrue
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.
