Smallest Number by Removing One Digit

Given a string consisting solely of digits ('0'-'9'), you are allowed to remove at most one digit in order to form the smallest possible number. The removal should be done such that the resulting number is minimized. If no removal makes the number smaller, then remove the rightmost digit. For example, for the input (15243), removing the digit '5' produces (1243), which is the smallest possible result.
