Hi! Helloneo. I can't understand why your output is correct....
fib[0]=1;
fib[1]=1;
fib =4*fib[i-2]+fib[i-1];

Then, for the fib[2]
fib[2]=4*fib[0]+fib[1]=4*1+1=5
fib[3]=4*fib[1]+fib[2]=4*1+5=9
fib[4]=4*fib[2 ...

Hi! How are all. I got WA in this exercise, and... i proof printing a "\n" in the final, and without thist "\n", and continue WA :-? . Somebody know why thist code have WA.
