Leetcode 3324. Find the Sequence of Strings Appeared on the Screen

Given a target string and a keyboard with only two operations (append "a" or cyclically increment the last character), simulate the minimal-key-press sequence that produces target and return every intermediate screen string; for each target character you append an "a" then repeatedly increment the last character (wrapping z→a) until it matches the target.
