The fibonacci sequence is a famous bit of mathematics, and it happens to have a recursive definition. The first two values in the sequence are 0 and 1 (essentially 2 base cases). Each subsequent value ...

nth term of Fibonacci series: fib(n)=fib(n-1)+fib(n-2 ... Here, the time complexity of algorithm is O(logN). The basic recursive algorithm O(N) time. To improve the time complexity, the method of ...
