738. Monotone Increasing Digits

Leetcode Solutions

Greedy Approach with Digit Manipulation

  1. Convert the integer n to a string s to easily access individual digits.
  2. Initialize a variable marker to the length of s.
  3. Iterate through the digits of s in reverse (starting from the second to last digit).
  4. If the current digit is greater than the next digit (to its right), decrement the current digit and set marker to the current index.
  5. After finding the first decreasing pair, set all digits to the right of marker to 9.
  6. Convert the modified string back to an integer and return it as the result.
