Hint

• This differs from the previous problem in just one point: this time do not keep the leading zeros (100 → 1). Of the two approaches from the previous problem, which one no longer works here?
• Digit-by-digit approach: assemble the reversed number as ones*100 + tens*10 + hundreds and print it as an integer.
• Verify with the samples: 100 → 1; 101 → 101.
