}
        public static int[] doInsertionSort(int[] input){
           
            int temp;
            for (int i = 1; i < input.length; i++) {
                for(int j = i ; j > 0 ; j--){
                    if(input[j] < input[j-1]){
                        temp = input[j];
                        input[j] = input[j-1];
                        input[j-1] = temp;
                    }
