Part I 1. The following is the sample code that shows two threads use mutex to communicate. Note mutex is a simplified semaphore. 1 of 4 Refer to this piece of sam code, write a program that conduct the ple followings (1) It contains two thread, t1 and t2 (2) t1 and t2 share a variable, myNum; (3) When my Nun is empty use a to show empty), t1 will generate a random number between 1 and 99, and save to myNum; (4) When my Nun is not empty, t2 will get this number and save it to an array, myNumArray, in ascending order. (5) After t2 insert a new number in myNunArray, it also shows the result mutex sample code using System using System-Collections.Generic; using System-Linq using System-Text using System.
