The TSA (Transportation Security Administration) at a major airport is evaluating a new policy of screening its customers. Current Policy (Policy 1): The TSA is managing three independent queues with one sever responsible for each queue. The customers arrive at the system and immediately are divided equally likely to each of the independent queues. New Policy (Policy 2): The new policy that TSA is preparing to implement is - pool all the three servers and manage the waiting of customers with a single queue. You are hired as an Operations analyst to evaluate both policies. The TSA has provided you with the following data - The inter-arrival time between customers arriving to the system and service time for each customer by a server follows an exponential distribution with a mean of 5 and 12 minutes respectively.

Public static int mystery(int a[], int x) {     int c = 0;     for(int i = 0; i < a.length; i++) {        if (a[i] == x) c++;     } return c; }the method counts how many times an integer shows up in an integer array.the c variable is declared in the method to keep track of how many times the certain value has shown up.the for-loop loops through the entire array.the line    if (a[i] == x) c++;   checks if each element of the array is equal to the inputted integer to check. for each number in the array that is equal to the inputted integer x, the c variable will be incremented by 1. otherwise it will do nothing.then c is returned at the end of the loop.for example, if we have, in the main method with the mystery method coded in the class:     int arraytest[] = {2, 23, 23, 23, 3};     int testme = 23;     int count = mystery(arraytest, testme);     system.out.println(count); then the print out will be    3 because there are three 23s in that array.

The correct answer is:

four
