Minimum Flips to Make the Binary String Alternate

Understand how to determine the minimum type-2 flips required to convert any binary string into an alternating pattern. Explore methods that involve character rotations and flipping bits to solve this problem optimally in linear time and constant space.

Statement

Given a binary string s, the following two operations can be performed in any sequence:

  • Type–1: Remove the character at the start of the string s and append it to the end of the string.

  • Type–2: Pick any character from the string and flip its value. in other words, if its value is 00, it becomes 1 ...
