(Single Digit) Complete the definition of the following function:singleDigit :: Int -> Int singleDigit takes a positive integer, num, as input and returns a digit between 0 and 9 as the output. The output is computed as follows: sum all the digits in num to obtain a result; if this result is less than 10 then result is the answer; otherwise take the result and apply the same procedure (i.e. sum its digits and compute a result, and so on). Here is a sample run:*Main> singleDigit 37425 3 *Main> singleDigit 9876543 6 Here is how the above answers are computed by hand:singleDigit 37425 => 3+7+4+2+5 = 21 => 2+1 = 3 singleDigit 9876543 => 9+8+7+6+5+4+3 = 42 => 4+2 = 6
