Task 3: Range Function Practice

Objective: Use Python’s range() to control loops.

Instructions:

1. Write a Python function range_sum(n) that:

• Uses a for loop and range() to add numbers from 0 up to n-1.

2. Modify the function to:

• Use a while loop instead of a for loop.

• Use a bottom-check loop (while True + break) structure to achieve the same.

Example Input:

n = 5

Expected Output:

Sum = 10
