The following pseudocode illustrates the basic push () and pop () operations of an array- based stack. Assuming that this algorithm could be used in a concurrent environment, answer the following questions: a. What data have a race condition? b. How could the race condition be fixed? push (item) { if (top SIZE) { } stack [top] = item; top++; else ERROR } pop () { if (!is_empty()) { } top--; return stack[top]; else ERROR } is_empty() { if (top == 0) return true; else return false; } Explain the following terminologies: a. race condition b. critical section c. mutual exclusion d. atomicity e. busy waiting f. deadlock g. starvation The following pseudocode illustrates the basic push () and pop () operations of an array- based stack.
