Absolute value
Problem
Write two multi-subroutines named abs-value that take an
integer and return its absolute value. Use a where clause
to handle the negative case separately — do not use any if
inside the subroutines, and do not use the built-in
abs.
Print the result for -7 and for 4.
Example
The program prints:
7
4
