Some computers have an instruction that atomically exchanges the values of two memory locations. It is defined as follows: Exchange(int var1, int var2): ⟨ int temp; temp = var1; var1 = var2; var2 = temp; ⟩ Above, temp is an internal machine register. Using Exchange, dev elop a solution to the critical section problem. In particular, giv ecode for CSenter and CSexit protocols that use the shared lock variable declared below. Y our solution does not have to be fair. shared variable: int lock = 0; CSenter: CSexit

Question
Some computers have an instruction that atomically exchanges the values of two memory
locations. It is defined as follows:
Exchange(int var1, int var2):
⟨ int temp; temp = var1; var1 = var2; var2 = temp; ⟩
Above, temp is an internal machine register.
Using Exchange, dev elop a solution to the critical section problem. In particular, giv ecode for
CSenter and CSexit protocols that use the shared lock variable declared below. Y our solution
does not have to be fair.
shared variable: int lock = 0;
CSenter:
CSexit
