Hey guys this is the fibonacci series. But Im having this huge problem.
First of all I want to do the simplest code possible so then I can use
user defined functions and arrays. But this one didnt came out well.
Any suggestions!
#include <stdio.h>
unsigned fib(unsigned n) {
return n <= 2 ? 1 : fib(n - 1) + fib(n - 2);
}
int main(void) { printf("fib(17) is: %d\n", fib(17)); return 0; }
Somebody always proposes this solution, but it's a
poor one. Try it with fib(47), say, and tell us how
long it takes. Hint: You won't need a high-precision
timer.
