Given a number n, find sum of first n natural numbers. To calculate the sum, we will use a recursive function recur_sum().
Input : 3 Output : 6 Explanation : 1 + 2 + 3 = 6 Input : 5 Output : 15 Explanation : 1 + 2 + 3 + 4 + 5 = 15
Below is code to find the sum of natural numbers up to n using recursion :
