evenSpaced

Question :

An integer array is said to be evenSpaced, if the difference between the largest value and the smallest value is an even number. Write a function isEvenSpaced(int[] a) that will return 1 if it is evenSpaced and 0 otherwise. If array has less than two elements, function will return 0. If you are programming in C or C++, the function signature is:

   int isEvenSpaced (int a[ ], int len) where len is the number of elements in the array.

Examples

Array	Largest value	Smallest value	Difference	Return value
{100, 19, 131, 140}	140	19	140 -19 = 121	0
{200, 1, 151, 160}	200	1	200 -1 = 199	0
{200, 10, 151, 160}	200	10	200 -10 = 190	1
{100, 19, -131, -140}	100	-140	100 - (-140 ) = 240	1
{80, -56, 11, -81}	80	-81	-80 - 80 = -161	0

Solution :

 public static int isEvenSpaced(int[] a)

        {

            int max = a[0], min = a[0];

            for (int i = 0; i < a.Length; i++)

            {

                if (max < a[i])

                {

                    max = a[i];

                }

                if (min > a[i])

                {

                    min = a[i];

                }

            }

            if ((max - min) % 2 == 0)

            {

                return 1;

            }

            else

            {

                return 0;

            }

        }
