Minimum printer operations
A printer can, in one operation, print a contiguous run of a single character, overwriting whatever was there. Given a target string s, return the minimum number of print operations needed to produce s starting from an empty (blank) canvas of the same length. 1 <= len(s) <= 100, s consists of lowercase letters.

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.
