Sum of 3 consecutive numbers in the input array - Java Quiz Question

Write a program to sum of consecutive 3 numbers in the input array.
NOTE: The input array size may NOT be a perfect multiple of 3.

Input (Integer Array)	Output (Integer Array)
`{2, 3, 4, 7, 6, 1}`	`{(2 + 3 + 4), (7 + 6 + 1)} = {9, 14}`
`{3, 9, 1, 5, 16, 10, 4}`	`{(3 + 9 + 1), (5 + 16 + 10), (4)} = {13, 31, 4}`
`{3, 9, 1, 5, 16, 10, 4, -6}`	`{(3 + 9 + 1), (5 + 16 + 10), (4 + -6)} = {13, 31, -2}`

	
		class SumOfThreeConsecutiveNumbersInArray	
			{    public static void main(String s[])
    {
        int[] input = {2, 6, 3, 8, 1};
        int[] output = sumOfThreeConsecutiveNumbers(input);
        System.out.print("Output array is : ");
        for(int i = 0; i < output.length; i++)
        {
            System.out.print(output[i] + ", ");
        }

    }
 
			

				public static int[] sumOfThreeConsecutiveNumbers(int[] input) 

				{ 

					int[] output = null; 

				//Write code here to sum of consecutive 3 numbers in input array and assign it to output 

					return output; 

				} 

			}
