* Fibonacci Sequence is*
0 1 1 2 3 5 8 13 21 34 55 89
Explanation
Iteration 1 :- a=0 b=1 c=a + b
3rd no(c) = 1st(a) + 2nd(b)
3rd no(c) = 0 +1 = 1
Iteration 2 :- a=1 b=1 c=a + b
4th no(c) = 2nd(a) + 3rd(b)
4th no = 1 +1 = 2
Sequence would be 0 1 1 2
Iteration 3 :- a=1 b=2 c=a + b
5th no = 3rd + 4th
5th no = 1 +2 = 3
Sequence would be 0 1 1 2 3
Code
a=0
b=1
n=int(input("Enter the no of elements in the Fibonacci Series:- "))
if n<0:
print("Enter the valid No")
elif n==0:
print(a)
elif n==1:
print(b)
else:
for i in range (n):
c=a+b
print(c,end=' ')
a=b
b=c
Output:-
