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 / listin 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 Output 84 Sample Input 110, 2, 13]. [4, 15, 16). [7.8. 91 [[15, 18). (4.171 Explanation Here, the summation of all the numbers is 84 Here, the summation of all the numbers is 54 54
