RecursionexerciseCOP 3502; Summer2021We have gone through many examples in the class and those examples are available in the slides and uploaded codes. Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:1.What would be the output of the following recursive function if we call rec2(5)

The output is:

1 2 3 4 5

Explanation:

Given

See attachment for code segment

Required

The output of rec2(5)

From the attached code segment, we have the following:

The base case: if (x==0){ return;}

The above implies that, the recursion ends when the value of x gets reduced to 0

The recursion:

rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function

printf("%d ", x); This prints the passed value of x

Hence, the output of rec2(5) is: 1 2 3 4 5
