Understand the problem
Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
Problem statement
Given two strings `s` and `t`, return `true` if `s` is a subsequence of `t`, or `false` otherwise. A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters.
Example
s = "abc", t = "ahbgdc" → true
Constraints
0 ≤ s.length ≤ 100 · 0 ≤ t.length ≤ 10⁴ · s and t consist only of lowercase English letters
