Fibonacci using tabulation easy Problem Statement Given a number n. Find the nth Fibonacci number using tabulation approach of DP. Note : For your reference fibonacci[0] = 0, fibonacci[1] = 1; In general fibonacci[n] = fibonacci[n-1] + fibonacci[n-2] So for n=5 the Fibonacci series would look like : 0 1 1 2 3 5 Input User Task: Since this will be a functional problem. You don\'t have to take input. You just have to complete the function fib() that takes a number n. You have to find the nth fibonacci number. Constraints: 0 <= N <= 40 Output Return the nth fibonacci number. Custom Input : Enter a number in the range 0<=n<=40 Custom Output : nth fibonacci number Example Input : 7 Output : 13 Explaination : Fibonacci series will be like : 0 1 1 2 3 5 8 13 Here Fibonacci[0] = 0 and hence Fibonacci[7] = 13
