Suppose you need to subtract a very large integer from another integer. This problem requires the player to add two long digits, both supplied as strings, and to return the sum as a string. This problem similarly provides two numbers as strings and you must return the difference as a string (a - b = c). The result will always be positive as a will be larger than b. See the test suite for examples.
