Write a method that accepts a non-empty array of non-negative integers and an integer "pos" indicating the position of the desired digit. The method returns the digit that appears at position "pos" where all the integers in the array are listed in the order they are given. For example getMyDigit({45, 8206, 53, 71}, 5) returns a 0 because if you list all the integers in order like this: 4582065371, the 5th digit is a zero. Note that the first digit is digit number 1, not digit number 0.
