Leetcode Solutions

Iterative Approach with Reverse Calculation

  1. Start a loop with i from 0 to num (inclusive).
  2. For each i, calculate the reverse of i.
    • Initialize reverse_i to 0.
    • While i is greater than 0:
      • Multiply reverse_i by 10 and add the last digit of i to reverse_i.
      • Divide i by 10 to remove the last digit.
  3. Check if the sum of i and reverse_i equals num.
    • If yes, return true.
  4. If the loop finishes without finding a valid pair, return false.
