Leetcode Problem 1888. Minimum Number of Flips to Make the Binary String Alternating

1888. Minimum Number of Flips to Make the Binary String Alternating

Leetcode Solutions

Double the input string s by concatenating it with itself.
Initialize two counters, diff0 and diff1, to track the number of flips required to match the alternating patterns starting with '0' and '1', respectively.
Initialize a variable minFlips to keep track of the minimum flips encountered.
Iterate through the characters of the doubled string using a sliding window of size equal to the original string's length.
For each character in the window, increment diff0 or diff1 if the character does not match the expected value in the alternating patterns.
If the window size exceeds the original string's length, decrement diff0 or diff1 for the character that is exiting the window.
Update minFlips with the minimum of diff0 and diff1 after the window has reached the original string's length.
Return minFlips as the result.
