Hello,

This is the Operating System problem. There is three software I must analyze code how it works. I must describe why one solution works and the other two does not work. I must anaylze every step. I must know where does dead lock happens. Which variable are waiting for the other one to get out to start its own critical section.

At least one of the following code segments is a solution to, the critical section problem. Analyze each segment with regard to the four constraints as listed on page 80 of the class handout. Note that constraint #1 is automatically satisfied. CLEARLY indicate which segment(s) is/are a solution(s) and which are not. Give CLEAR and CONCISE reasons for EACH of your conclusions.
