Top Forums Shell Programming and Scripting Shell script to generate Fibonacci series using recursion Post 302378728 by jstrangfeld on Tuesday 8th of December 2009 03:41:32 PM

I guess recursion is a requirement? It sure seems inefficient.

Your script using recursion:
Code:
$ time ./fibo2.sh
Enter the number of term : 10
0 1 1 2 3 5 8 13 21 34 55

real    0m14.875s
user    0m8.454s
sys     0m4.765s

Mine not using recursion:
Code:
$ time ./fibo.sh
Enter the number of term : 10
Fibonacci (10)=55

real    0m1.817s
user    0m0.046s
sys     0m0.030s
