2134. Minimum Swaps to Group All 1's Together II

Leetcode Solutions

Count the number of 1's in the original array and store it as ones.
Double the array by appending it to itself.
Initialize maxOnesInWindow to 0, which will keep track of the maximum number of 1's in any window.
Use a sliding window of size ones to traverse the doubled array.
For each window, count the number of 1's within it and update maxOnesInWindow if the current count is greater.
After traversing all windows, calculate the minimum swaps as ones - maxOnesInWindow.
Return the minimum swaps.
