Write a program that consists in three processes to print the message "ping-pong" two times on screen. The main process creates two processes Ping and Pong (Ping can only print "ping" and Pong can only print "pong"), then wait for them to finish, Use the following pipes to synchronize Ping and Pong Ping Pong Hint: To make a process waits, let it read from an empty pipe, so it will wake after finding a new information in the pipe. up The main process is not allowed to print on screen.

JAVA LANGUAGE PLS THANK YOU 1. Squares by CodeChum Admin Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this! Instructions: Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line. Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition. Input Multiple lines containing an integer. 2 6 0 Output Multiple lines containing an integer. 4 36 0
python programmingprogram a clock using nested repeat loops.• The minute hand must contain the second hand.• When the second hand reaches 59, the minute hand has to be increased one by one.• The maximum value of the clock will be one hour (1:00:00).• Don't forget to delete variables when 59 is reached.

Assume n is a positive integer. Consider the loop below: x := 0 for i:= 5 to 5n x = 2(x+i) - 7 next i There are the total number of operations performed in this loop is operations performed in each run of the loop and the loop runs times, so
In Java A while loop reads integers from input. Write an expression that executes the while loop until a positive integer is read from input. Ex: If the input is -20 -43 -25 -22 15, then the output is:User entered -20User entered -43User entered -25User entered -22Loop terminated while () {

Instructions Write the pseudocode and draw the flowchart of the solution for each of the following problems:
Examine the following for loops and determine the value of ires at the end of each of the loops, and also the number of times each loop executes.
a. int i = 2; while (i 8) int i = 2; break; while (i <= 4) System.out.println (i++); d. int i = 2; while (i <= 5) System.out.println (i++);
Build a flowchart for this programming exercise. Use a While loop instead of a For loop
Python Programming: You are roaming in a random city and you have lost. You see a sign board and where that is return is that you can go to X and Y street if 1 <= Y - X <= K, where K is a value that is written on the board. You have to reach to your hotel in such a way that it is minimal. Input Output 31 10 251
Subject: Assembly Language Q: Write a program that displays a string in all possible combinations of foreground and background colors (16 x 16 =256). The colors are numbered from 0 to 15, so you can use a nested loop to generate all possible combinations. Also use a delay of 1s in each foreground color change.
