Consider the following proposed solution for the critical section problem. There are n processes: P0…Pn – 1. In the code, function pmax returns an integer not smaller than any of its arguments. For all i, t[i] is initialized to zero. Code for Pi: do {                 c [i]=1; t[i] = pmax (t [0],…, t[n-1]) +1; c[i]=0;                 for every j ≠ I in {0,…,n-1} {                                 while (c[j]);                                 while (t[j] != 0 && t[j]<=t[i]) ;                 ]                 Critical section;                 t[i] =0;                 Remainder Section; } While (true); Which one of the following is TRUE about the above solution?
