Suppose a computer has atomic decrement DEC and increment INC instructions that also return the value of the sign bit of the result. In particular, the decrement instruction has the following effect: DEC(var, sign): 0) sign = 0; else sign = 1; > INC is similar, the only difference being that it adds 1 to var. Using DEC and/or Inc, develop a solution to the critical section problem for n processes. Do not worry about the eventual entry property. Describe clearly how your solution works and why it is correct Suppose a computer has atomic decrement DEC and increment INC instructions that also return the value of the sign bit of the result.
