Python Data Structures and Algorithms - Recursion: Calculate the geometric sum
Python Recursion: Exercise-9 with Solution
Write a Python program to calculate the geometric sum of n-1.
Note : In mathematics, a geometric series is a series with a constant ratio between successive terms.
def geometric_sum(n): if n < 0: return 0 else: return 1 / (pow(2, n)) + geometric_sum(n - 1) print(geometric_sum(7)) print(geometric_sum(4))
