Algorithm to print Fibonacci series up to given number N.

About Fibonacci series 

Each new number in a series is addition of its previous two numbers.

Example of Fibonacci series(for N = 8)

0, 1, 1, 2, 3, 5, 8, 13

Algorithm to print Fibonacci series up to given number N.

Step 1: Start

Step 2: Declare variables N, N1, N2, N3, i.

Step 3: Read value of N from user.

Step 4: if N < 2, display message “Enter number > 2” and go to step 9.

Step 5: Initialize variables N1 = 0, N2 = 1, i = 0

Step 6: Display N1, N2  

Step 7: Compute N3 = N1 + N2

Step 8: Repeat following statements until i <  N - 2

Display N3

N1 = N2

N2 = N3  

N3 = N1 + N2

i  = i + 1

Step 9: Stop
