Write a method that returns the sum of the digits in the one's place of 'a' and the one's place of 'b'. For example, if a=2417 and b=93251 you would return 8 since 7+1=8. The 7 was taken from the one's place of a, while the 1 was taken from the one's place of b. Look at the test data for further examples. Don't forget about "mod", which is the "%" operator. As a precondition, you may assume that a>0 and b>0. NOTE: NO strings are allowed! You may NOT use strings to solve this problem.
