)Let N be a number of processes running simultaneously in a computing system. Each of the processes increments the value of a shared variable total by 2 once, as shown in the code snippet below. Notice that no shape is used of mutual exclusion in the code. Shared variables int total = 0; Code that executes each of the N processes total = total + 2; Answer the following two questions. a. What is the smallest value that the total variable can take? b. What is the largest value that the total variable can take?
