Python Data Structures and Algorithms - Recursion: Sum of a list of numbers

Python Recursion: Exercise-1 with Solution

Write a Python program to calculate the sum of a list of numbers using recursion.

Sample Solution:

Python Code:

# Define a function named list_sum that takes a list of numbers as input
def list_sum(num_List):
    # Check if the length of the input list is 1
    if len(num_List) == 1:
        # If the list has only one element, return that element
        return num_List[0]
    else:
        # If the list has more than one element, return the sum of the first element
        # and the result of recursively calling the list_sum function on the rest of the list
        return num_List[0] + list_sum(num_List[1:])

# Print the result of calling the list_sum function with the input [2, 4, 5, 6, 7]
print(list_sum([2, 4, 5, 6, 7]))

Sample Output:

24
