in code c++ describe a recursive algorithm for multiplying two
nonnegative integers x and y based on the fact that xy = 2(x ·
(y/2)) when y is even and xy = 2(x · ⌊y/2⌋) + x when y is odd,
together with the initial condition xy = 0 when y = 0.

Write, in Python, a recursive algorithm that takes, as input, a
positive integer n, and returns, as output, the sum of the first n
positive odd integers. Your solution should be recursive, and it
should not contain any "for" loops or "while" loops.

The factorial of a nonnegative integer n is written n!
(Pronounced “n factorial”) and is defined as follows: n! = n.(n-1).
(n-2).……...1 (for values of n greater than 1) n!=1 (for n = 0 or
1)
For instance, 5! = 5.4.3.2.1 which is 120.
Write a Python program that reads a nonnegative integer n and
calculates and prints its factorial. Your program should display a
suitable error message if n entered as a negative integer.

In mathematics, the
notation n! represents the factorial of the nonnegative
integer n. The factorial of n is the product of
non-negative numbers from 1 to n.
Design a program that
asks the user to enter a nonnegative integer and then displays the
factorial of that number.

loop is used to require user input until a nonnegative number is
entered. Once a nonnegative number is entered, the integer is...
