Minimum Flips

Problem Overview

• Find the minimum flips to transform an all-zero string into a target binary string, where flipping a position toggles it and all digits to its right.
• Input: target (string of '0'/'1'); Output: integer count of flips; constraints: length 1 to 1e5.
• Applies to bit/state toggling scenarios in systems like switches, feature flags, or signal control.
• Asked in IBM interviews; a classic coding interview problem and interview question.
