removeLeadingZeroes

Define a recursive function that when passed a String (assume it represents a non-negative integer), returns the number with leading zeroes removed.

removeLeadingZeroes("001729") → "1729"
removeLeadingZeroes("000000000000000000000000123450000012345") → "123450000012345"
removeLeadingZeroes("00000000000") → "0"
