(a) Write a method public static void insert(int[] a, int n, int x) that inserts x in order among the first n elements of a, assuming these elements are arranged in ascending order. Do NOT use arraylists. x is the last element in a. n does not include x. (b) Using the insert method from Part (a), write a recursive implementation of Insertion Sort.

Write a RECURSIVE function, without using any loops, that prints the contents of a matrix with 3 columns. The function should take the matrix and the number of rows as arguments. void print_matrix(int arr[][3], int num_rows);

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

An array int[] intArray can be initialized during its definition by A.) It can't be initialized B.) by writing int[] intArray = {1.0f}; C.) by writing int[] intArray = {0,1,2}; D.) by writing int[0-10] intArray = {0,1,2,3,4,5,6,7,8,9};
