Write a method named digitSum that accepts an integer as a parameter and returns the sum of the digits of that number. For example, digitSum(29107) returns 2+9+1+0+7 or 19. For negative numbers, return the same value that would result if the number were positive. For example, digitSum(-456) returns 4+5+6 or 15.
