The Fibonacci Sequence is computed based on the following formula:
f(n)=0 if n=0
f(n)=1 if n=1
f(n)=f(n-1)+f(n-2) if n>1
Please write a program using list comprehension to print the Fibonacci Sequence in comma separated form with a given n input by console.
Example:
If the following n is given as input to the program:
7
Then, the output of the program should be:
0,1,1,2,3,5,8,13
Hints
We can define recursive function in Python.
Use list comprehension to generate a list from an existing list.
Use string.join() to join a list of strings.
In case of input data being supplied to the question, it should be assumed to be a console input.
Solution
def f(n):
if n == 0: return 0
elif n == 1: return 1
else: return f(n-1)+f(n-2)
n=int(raw_input())
values = [str(f(x)) for x in range(0, n+1)]
print ",".join(values)
