Write a method that has two string parameters 'first' and 'last'. As a precondition, you may assume that 'last' will be AT LEAST as long as 'first' and could be even longer. Your goal is to return a string that combines all of the characters from 'first' with an equal length of characters from 'last'. For example, if 'first' was "testing" and 'last' was "on the computer" you would return "testingon the ". This is because 'testing' contains 7 characters, so you must use the first 7 characters from "on the computer". Look at the test data for more examples.
