 write a recursive function that solves the equation X[n] = X[n-1] + X[n-2] where X is an array that contains at least two integer values and the function should solve the question for the 3rd value in the array2 AnswersI'm guessing a key element they want to see in your answer is that you realize there's a lot of recalculating the same values over and over in the recursion process, especially for large values of n. For example, x[5] = x[4] + x[3] x[4] = x[3] + x[2] x[3] = x[2] + x[1] x[2] = x[1] + x[0] x[1], x[0] are known x[1] is known x[2] = x[1] + x[0] x[1], x[0] are known x[3] = x[2] + x[1] x[2] = x[1] + x[0] x[1], x[0] are known x[1] is known If you cache a couple of values in the recursive function, you can improve performance significantly. You might also get some points for recognizing this can be used to generate the Fibonacci sequence.yes its a fibonacci series problem solved using recursion and memoization, classic example of dynamic programming. without caching runtime is exponential.
