Python Data Structures and Algorithms - Recursion: Sum of n+(n-2)+(n-4)...
Python Recursion : Exercise-7 with Solution
Write a Python program to calculate the sum of the positive integers of n+(n-2)+(n-4)... (until n-x =< 0).
Sample Solution:
Python Code:
def sum_series(n):
if n < 1:
return 0
else:
return n + sum_series(n - 2)
print(sum_series(6))
print(sum_series(10))
Sample Output:
12 30
