I can't figure out where my code got wrong

Hello @coe17b030,

  1. Your code is failing for the test case like:
    1
    2
    9 96
    Expected output:
    996

  2. Output of each test case should be on a different line.
    2
    2
    9 96
    4
    54 546 548 60
    Expected output:
    996
    6054854654

Hope, this would help.
Give a like, if you are satisfied.
