Let s be a string that contains a sequence of decimal numbers separated by commas

INSTRUCTIONS TO CANDIDATES
ANSWER ALL QUESTIONS

1. (30 points) Let s be a string that contains a sequence of decimal numbers separated by commas, e.g., s='1.23,2.4,3.123'. Write a Python code that gets s from a user using the input statement and prints the sum of the numbers in s. You may use a while statement to find the commas in the string, extract one number in each execution of the loop and sum the numbers after all of them are extracted. You may use the built-in string method, find.

2. (30 points) Consider the recursive function, f(x), such that f(0) = √π and f(x + 1) = (2x+1)f(x)/2, meaning that f(1) = √π/2, f(2) = 3√π/4, etc. Write a Python code that computes this function for a given value of x. The code is expected to get a nonnegative integer, x, from a user using the input statement. It is expected to have a recursive function to compute f(x) and print it. Using a regular function instead of a recursive function will cause loss of points. Assume that the user correctly enters a nonnegative integer so that the code does not have to check if it is properly entered.
