Answer:

Explanation:

Anything "factorial" is the result of multiplying the number by itself and all numbers below it, so:

4! = 4 × 3 × 2 × 1 = 24

There's no other info for this question so I assume you just wanted the answer, but as an example of a program here's a function that would work it out for you by using recursion in javascript, to use this you would call factorial(4) like at the bottom:

function factorial(num) {

if (num < 0)

return -1;

else if (num == 0)

return 1;

else {

return (num * factorial(num - 1));

}

factorial(4);

Add the following binary numbers. 101110010 and 111001101

bonufazy [111]

Answer:

101110010 is 370 in decimal (base 10, what we usually do math in) and 111001101 is 461 in decimal. The sum of 370 and 461 is 831, and 831 is binary is 1100111111. So, if you want the answer in decimal it is $\boxed{831_{10}}$ and if you want the answer in binary, it is $\boxed{1100111111_2}$ .

Write a program that plays the popular scissor-rockpaper game. (A scissor can cut a paper, a rock can knock a scissor, and a pap

kolbaska11 [484]

Answer:

import random

computer = random.randint(0, 2)

user = int(input("scissor (0), rock (1), paper (2): "))

if computer == 0:

if user == 0:

print("The computer is scissor. You are scissor too. It is a draw")

elif user == 1:

print("The computer is scissor. You are rock. You won")

elif user == 2:

print("The computer is scissor. You are paper. Computer won")

elif computer == 1:

if user == 0:

print("The computer is rock. You are scissor. Computer won")

elif user == 1:

print("The computer is rock. You are rock too. It is a draw")

elif user == 2:

print("The computer is rock. You are paper. You won")

elif computer == 2:

if user == 0:

print("The computer is paper. You are scissor. You won")

elif user == 1:

print("The computer is paper. You are rock. Computer won")

elif user == 2:

print("The computer is paper. You are paper too. It is a draw")

Explanation:

*The code is in Python.

Import the random to be able to generate number number

Generate a random number between 0 and 2 (inclusive) using randint() method and set it to the computer variable

Ask the user to enter a number and set it to the user variable

Check the value of computer the computer variable:

If it is 0, check the value of user variable. If user is 0, it is a draw. If user is 1, user wins. If user is 2, computer wins

If it is 1, check the value of user variable. If user is 0, computer wins. If user is 1, it is a draw. If user is 2, user wins

If it is 2, check the value of user variable. If user is 0, user wins. If user is 1, computer wins. If user is 2, it is a draw
