Given the headRecursion Sourcecode below; refactor the code to create the source code for tailRecursion.

Note: In tailRecursion, the recursive calls are executed last.

tailRecursion Output

Recursive calls (if statement) are skipped

Recursive calls (if statement) are executed last due to being tail recursion

Recursive calls (if statement) are executed last due to being tail recursion
