how would you implement this using the scheme programming language? (comments also helpful)

abs is a built-in function that takes an argument and returns the absolute value of the argument. For example, > (abs 3.22) 3.22 > (abs -5.16) 5.6 > (abs -2) 2 Write a function that takes a list as an argument and returns a list of absolute values of each of the elements. Assume the list will contain 0 or more numbers and no sublists. Built-in functions map or apply cant be used.

no python i will down vote and report any answers given in python.
