Find Last Non-Zero Character and Substring

  1. Initialize an index variable i to the last index of the string.
  2. Iterate backwards through the string using a while loop.
  3. Inside the loop, check if the current character is '0'.
  4. If it is not '0', break out of the loop as we have found the last non-zero character.
  5. If it is '0', decrement the index i.
  6. After the loop, use the substring method to get the string from index 0 to i + 1.
  7. Return the resulting substring.
