6.7 The pseudocode of Figure 6.16 (at page 364 of PDF file) 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; } Figure 6.16 Array-based stack for Exercise 6.12.
