Create a method that takes an array of integers called 'nums'. This array will contain all the numbers from 1 to some maximum number in order, but excluding one number. The excluded number could be 1 or any ONE number in the middle. The excluded number will NOT be the last number. Return the missing number. For example, if 'nums' was {1,2,3,4,5,7,8,9,10} you would return 6 since that is the missing number. Look at the test data for other examples.
