Leetcode Problem 1850. Minimum Adjacent Swaps to Reach the Kth Smallest Number

1850. Minimum Adjacent Swaps to Reach the Kth Smallest Number

Leetcode Solutions

Next Permutation and Counting Swaps

  1. Convert the input string num into a list of characters for easier manipulation.
  2. Apply the next permutation algorithm k times to find the kth smallest wonderful integer.
  3. Initialize a variable to keep track of the total number of swaps.
  4. Iterate through each character of the original number and the kth permutation.
  5. For each mismatch found, locate the position of the needed character in the kth permutation.
  6. Perform swaps in the kth permutation to bring the character to the correct position, incrementing the swap count accordingly.
  7. Continue until the original number is transformed into the kth permutation.
  8. Return the total number of swaps.
