The below defined function is about sum of the first n whole numbers.def sum_of_numbers(n):       if n==0:          return 0       else:          return fThen what is f?1 pointA.f is (n-1)+sum_of_numbers(n)B. f is n-1+sum_of_numbers(n-1)C. f is n+(n-1)+sum_of_numbers(n-2)D. f is n+(n-1)+(n-2)+sum_of_numbers(n-3)E. f is any one of the B, C and D

Consider a Python function that computes the sum of all numbers from 1 to n by repeatedly calling itself with n-1 until it reaches 1. What type of function is this?

A function, sumN, is defined that takes an integer n as argument and returns the sum of the integers from 1 through n. Write a C program to determine value of the expression shown below?  sumN(3456) - sumN(3455)Note: the arguments of function sumN() can be obtained from user at runtimeTestcases:Input:18041604Output:2Input:34563455Output:1

Sum of NumbersYou are given a Python code snippet that aims to find the sum of all numbers from 1 to a given positive integer n. However, some parts of the code are missing. Fill in the missing code to complete the program.Sample Test CasesTest Case 1:Expected Output:Enter·a·positive·integer:·3The·sum·of·all·numbers·from·1·to·3·is:·6Test Case 2:Expected Output:Enter·a·positive·integer:·5The·sum·of·all·numbers·from·1·to·5·is:·15

create a Python script with a recursive function to display the sum of the first n integers, where n is entered by the user. There is no need to create a class similar to how Java works. 2. Name your function find_sum.
