I want answer in python without using built-in function as mentioned in question.

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 maximum number 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 first FunctionMax (arr, indexl, index2, max): #To Do return OR public int firstFunctionMax (int[] [] arr, int indexl, int index2, int max) { //To Do return Sample Input Sample Output Explanation 16 [[10, 2, 13], [4, 15, 16]. [7, 8, 9]] Here, in the list the maximum number is 16. [[15, 18], [4, 171] 18 Here, in the list the maximum number is 18
