Unlock the Power of Recursion: Calculating the Sum of Natural Numbers
When it comes to tackling complex problems in Python, understanding recursion is key. By harnessing the potential of recursive functions, you can simplify even the most daunting tasks. In this example, we’ll explore how to calculate the sum of natural numbers up to a given number using a clever recursive approach.
The Magic of Recursive Functions
Meet recur_sum(), a custom function designed to compute the sum of natural numbers up to a specified limit. This ingenious function leverages the power of recursion to break down the problem into manageable chunks.
Source Code Breakdown
Take a closer look at the program below:
“`
def recursum(num):
if num == 0:
return 0
else:
return num + recursum(num – 1)
num = 10
print(“Sum of natural numbers up to”, num, “is”, recur_sum(num))
“`
Output and Customization
Run the program to see the output:
Sum of natural numbers up to 10 is 55
Want to test the program with a different number? Simply modify the value of num to see the results.
