WebOct 27, 2013 · Moreover, if the programmer is the person who is writing code to solve critical section problem, then as per peterson's solution the entry section of this code uses shared variables themselves. These shared variables should then also be critical sections and we would need to restrict access to them as well. WebCh-61. The first known correct software solution to the critical-section problem for n processes with a lower bound on waiting of n − 1 turns was presented by Eisenberg and McGuire. The processes share the following variables:enum pstate { idle, want_in, in_cs}; pstate flag [n];int turn;All the elements of flag are initially idle.
