$1.$ Control access to a shared variable: $(30$ points$)$ Download the thread$-$based application file $($P$1.$c$).$ The application creates $2$ threads: one increments the global variable someValue a number of times $($COUNT$),$ and another decrements someValue the same number of times. Compile and run P$1.$c and answer the following questions: a$.$ What should the final value for someValue be$?$ What does the program print as the final value for someValue? b$.$ Increment COUNT to $100,1000,10000,$ and compile and run the code. In each case, what does the program print as the final value for someValue? Explain the reason behind the discrepancy in the output. c$.$ Update the code to solve the problem.
