Question 1 Suppose you have to design a number calculation system. You need to write a recursive function that will take a 2 dimensional array / list(in python) of numbers. You need to find the summation of all the numbers of the array / list using a recursive function. Implement the following recursive function. [You can not use any loop in the code]. Hint: You will need nested recursive functions. [Note for Implementation: You are not allowed to use any built-in functions except len() and print() in Python and any kind of global/class variable) def firstFunctionSum (arr, indexl, index2): #To Do return OR Public int firstFunctionSum (int[][] arr, int indexl, int index2) { //To Do return } Sample Input Sample Output 84 [[10, 2, 13], [4, 15, 16), [7, 8, 9]] [[15, 18], [4, 17]] Explanation Here, the summation of all the numbers is 84 Here, the summation of all the numbers is 54 54
