Leetcode Problem 2340. Minimum Adjacent Swaps to Make a Valid Array

2340. Minimum Adjacent Swaps to Make a Valid Array

Leetcode Solutions

Find Minimum and Maximum Indices and Calculate Swaps

  1. Initialize minIndex to -1 and maxIndex to the length of the array.
  2. Iterate through the array to find the first occurrence of the minimum element and update minIndex.
  3. Iterate through the array to find the last occurrence of the maximum element and update maxIndex.
  4. Calculate the number of swaps needed to move the maximum element to the end as len(nums) - 1 - maxIndex.
  5. Calculate the number of swaps needed to move the minimum element to the beginning as minIndex.
  6. If minIndex is greater than maxIndex, subtract one from the total number of swaps.
  7. Return the total number of swaps.
