In java-Write a function nthDigit, which takes in two ints, n and num, and returns the n th highest order digit of num. In other words, this method returns the n th digit from the left, as opposed to nthDigitBack, which returns the n th digit from the right. The leftmost digit is considered the 0th digit here. Just like nthDigitBack, nthDigit should evaluate to 0 for digits beyond the end of the number.

Think about how to convert the problem of the n th digit from the left into finding the same digit, but going from the right. Example method calls:

nthDigit(0,123) 1

nthDigit(1,123) 2

nthDigit(2,123) 3

nthDigit(3,123) 0

nthDigit(0,0) 0

nthDigit(3,18023) 2
