lua &jit lua <br/> <br/>function fibonacci(n,acc1,acc2) <br/> if n == 0 then <br/> return acc1 <br/> end <br/> return fibonacci(n - 1,acc2,acc1+acc2) <br/>end <br/> <br/>io.write(fibonacci(40,1,1), “\n”)

very interesting!


How about C++ meta programming, it’s a bit of cheating :-) <br/> <br/>$ g++ <br/>$ time ./a.out <br/>165580141 <br/> <br/>real 0m0.003s <br/>user 0m0.001s <br/>sys 0m0.002s <br/> <br/> <br/>#include <br/> <br/>template <br/>struct fibonacci { <br/> enum { Result = fibonacci::Result + fibonacci::Result }; <br/>}; <br/> <br/>template <br/>struct fibonacci { <br/> enum { Result = 1 }; <br/>}; <br/> <br/>template <br/>struct fibonacci { <br/> enum { Result = 1 }; <br/>}; <br/> <br/>int main(int argc, char *argv[]) <br/>{ <br/> printf("%d\n", fibonacci::Result); <br/> return 0; <br/>}

尖括号都没了…… <br/>上面的代码看这里
