动态数组求和

 public static void main(String[] args) {
        System.out.println(Arrays.toString(runNums(new int[]{1, 2, 3, 4, 5, 6})));
    }

    public static int[] runNums(int[] nums){

        for (int i = 0; i < nums.length-1; i++) {
            nums[i + 1] += nums[i];
        }

        return nums;
    }
