Java Foundations Consider the following Java method to reverse an array, i.e. rearrange its elements to the opposite order. An array containing {1, 3, 5} would contain {5, 3, 1} after being reversed. public static void arrayReverse(int[] array) { int le, ri; for (le = 0, ri = array.length - 1; le < array.length / 2; le++, ri--) { int temp = array[le]; array[le] = array[ri]; array[ri] = temp; } } Write the worst-case runtime efficiency of arrayReverse in BigOh notation.

This is a subclass and doesn't has a main method yet. class Vector{Object items[];int length;int size; void Grow(){// Duplicate sizesize = size * 2; // Allocate new itemsObject new_items[] = new Object[size]; // Copy old itemsfor (int i = 0; i < length; i++)new_items[i] = items[i]; // Discard old itemsitems = new_items; // MessageSystem.out.println("Growing capacity to " + size + " elements");} public Vector(){size = 2;items = new Object[2];} public void Print(){// MessageSystem.out.println("Content:"); // Traversefor (int i = 0; i < length; i++)System.out.println(items[i]);} public void Insert(int index, Object item){// Check indexif (index < 0 || index > length){System.out.println("Invalid index");return;} // Grow if necessaryif (length == size)Grow(); // Shiftfor (int i = length - 1; i >= index; i--)items[i + 1] = items[i]; // Insertitems[index] = item; // One more itemlength++; // MessageSystem.out.println("Inserted " + item);} public void Add(Object…

Refer to the following method that finds the smallest value in an array. /** Precondition: arr is initialized with int values. * Oparam arr the array to be processed Greturn the smallest value in arr public static int findMin(int[] arr) { int min = /* some value */; int index = 0; while (index < arr.length) { if (arr [index] < min) min = arr [index]; index++; } return min; } Which replacement(s) for /* some value */ will always result in correct execu- tion of the findMin method? I Integer.MIN_VALUE II Integer.MAX_VALUE III arr [0] (A) I only (B) II only (C) III only (D) I and III only (E) II and III only
