I wanted to compute 80th term of the Fibonacci series. 1: fib(n-1) + fib(n-2); } and waited for the result. I wait... I wrote the rampant recursive function, int fib(int n){ return (1==n -- 2==n) ?
and wait...With an 8GB RAM and an Intel i5 CPU, why is it taking so long? and wait... I terminated the process and tried computing the 40th term.
It took about a second. I put a check and was shocked to find that the above recursive function was called 204,668,309 times while computing the 40th term.More than 200 million times? Is it reporting function calls or scam of some government?The Dynamic Programming solution computes 100th Fibonacci term in less than fraction of a second, with a single function call, taking linear time and constant extra memory.A recursive solution, usually, neither pass all test cases in a coding competition, nor does it
