Yoda has a list of numbers. At most, two of the numbers in the list will match. The list will have less than 100 numbers in it. Return an integer representing the position in the list of the two matching numbers. The 1000's and 100's place will be the position in the list of the lower indexed number, except that each index will start at 1 instead of 0. The 10's and 1's place will be the position of the higher indexed number, again starting at 1 instead of 0. For example, in the list {3, 7, 3}, the matching numbers are in index 1 and index 3. 103 will be the value that gets returned. Suppose the matching numbers are at index 31 and index 50... in that case return 3150. Look at the test data for further examples. If no numbers match in the list, return -1.
