Question

Below is the example of the code snippet which needs the help

Example:

[1,2,3,4,5]

• if the chunk size is 1,

Answer 1

        import java.util.Arrays;

        public class ArrayChunk {

            public static void main(String[] args) {

                int[] array = {1,2,3,4,5};

                
                 int[][] chunks1 = ArrayChunk(array, 1);
                 print(chunks1);
                 int[][] chunks2 = ArrayChunk(array, 2);
                 print(chunks2);
                 int[][] chunks3 = ArrayChunk(array, 3);
                 print(chunks3);

                 
                 
            }

            public static int[][] ArrayChunk(int[] array, int chunkSize) {
                int numOfChunks = (int) Math.ceil((double) array.length / chunkSize);
                int[][] output = new int[numOfChunks][];

                for (int i = 0; i < numOfChunks; i++) {
                    int start = i * chunkSize;
                    int length = Math.min(array.length - start, chunkSize);

                    int[] temp = new int[length];
                    System.arraycopy(array, start, temp, 0, length);
                    output[i] = temp;
                }

                //
                return output;
            }

            private static void print(int[][] output) {
                //
                System.out.println("======================");
                for (int[] x : output)
                    System.out.println(Arrays.toString(x));
            }
            

        }



        ======================
        [1]
        [2]
        [3]
        [4]
        [5]
        ======================
        [1, 2]
        [3, 4]
        [5]
        ======================
        [1, 2, 3]
        [4, 5]
