2 test case not passed! in chewbacca and number

#1

sir ,please see my code in collaboration mode ,my test cases are geting failed!

#2

where is your code? can you please share it?
the most probable error in this question is a corner case where all the digits are 9, or first digit is 9.(solution: first 9 should be untouched)
check your code for following examples:(left side is input, right side is expected output)

  1. 999 ----> 900
  2. 987 -----> 912
  3. 9 -------> 9

thanks
