Write a method that accepts an input parameter containing an array of non-negative integers called 'nums'. Return an array of integers, where the index in the array represents a digit, and the value stored at that index represents how many times that digit appeared in any of the numbers in the 'nums' array. For example, if the input array contained: {25, 52, 755} you would return {0, 0, 2, 0, 0, 4, 0, 1, 0, 0}. Notice, for example, why the resulting array contains a 4 at index 5. This is because the digit '5' appears a total of 4 times in the 'nums' array.
