if n==0:

else:
return f(n-1)+10
print(f(5))

Answer 1

Shreepriya HA this is a recursive just like in my c program only it is in python.

This is an inductive definition of a function f,
f(n) = f(n-1)+10
with base case, f(0)=0;

In order to understand what this code does, let's see how this gets executed

>>f(5) = f(4)+10

>>f(5) = (f(3)+10)+10
{because f(4)= f(3)+10}

Similarly,
f(5) = (f(2) +10) +10 + 10
f(5) = (f(1) +10) +10 + 10 + 10
f(5) = (f(0) +10) +10 + 10 + 10 +10
So, f(5) = 50

This code will output 50
