JAVA PROGRAMMING, WILL GIVE BRAINLIEST, PLS Here are the instructions:
Debug the program so it prints the factorial of a positive integer entered by the user. This is calculated by multiplying all the numbers from 1 up to that number together. For example, 5 factorial is 5*4*3*2*1 = 120.

Here is the code:
import java. util. Scanner;

public class U4_L1_5_Activity_Two{
public static void main(String[] args){

Scanner scan = new Scanner(System. in);
int num = scan. nextInt();
while(num >= 0){
int prod = 1;
num--;
prod = prod*num;
}
System. out. println(prod);

}
}

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.

The most accurate readings that you can take on an analog vom are when the meter's pointer is at the a. center scale. b. extreme right. c. near right. d. extreme left.
