Question

Exercises: Solve the following problems on paper and bring your sheet of paper to your section on Thursday: Consider the following method: public static void arrayMystery(int[] array) { for (int i = 0; i < array.length - 1; i++) { if (array[i] < array[i + 1]) { array[i] = array[i + 1]; } } } Indicate what values would be stored in the array after the method arrayMystery executes if each integer array below is passed as a parameter to it. a. input = {2, 4} b. input = {1, 3, 6} c. input = {7, 2, 8, 4} d. input = {5, 2, 7, 2, 4} e. input = {2, 4, 6, 3, 7, 9}

Answer 1

Answer:

Hi Lzvcorri! Based on the inputs, we can expect the answers:

a. [4, 4]

b. [3, 6, 6]

c. [7, 8, 8, 4]

d. [5, 7, 7, 4, 4]

e. [4, 6, 6, 7, 9, 9]

Explanation:

For a, the input is {2,4} so the array length is 2, and the loop will run for array.length - 1. So the first run with this array will see if array[i] (i=0 as initially set in the for loop with the statement "for (i=0;)") is less than the value in the array after it, array[i+1]. Since 2, is less than 4, it will assign the value of 4 in the first array index as per this condition being met (array[i] = array[i + 1];). Similarly, if you trace the execution of the program with the remaining inputs b, c, d, and e, you should expect the resultant array as in the answer above.
