The following is the structure of process P_i from an algorithm attempting to solve the two-process critical section problem. while (1) {while (turn !=i); critical section turn = j remainder section} where turn is a shared integer variable, i is an integer zero or one and represents the index of Process P_i, j is an integer zero or one and represents the index of the other running Process P_j. (a) What is the problem with this algorithm? (b) How can it be fixed? (c) Write the structure of process P_i that solves the two-process critical
