Compare the Array

Ram Prasad

Compare two arrays A and B one number at a time. Array A has numbers from 1 to 16 and Array B has number 4,8,12 and 15. one number should be compared at a time. In no match show 0 if matches show number. Next number in B must be compared from next number to the previous match.

Ex- If previous match was at N+3 next comparison must start from N+4 and result should show 0,0,0,4,0,0,0,8,0,0,0,12,0,0,15,0.

Hi,

Please get the perfect out which you want.
static void Main(string[] args)
        {

            int[] a = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };
            int[] b = new int[] { 4, 8, 12, 15 };

            int c = 0; int d = 0;
            for (int i = 0; i < a.Length; i++)
            {
                c = 0;  d = 0;
                for (int j = 0; j < b.Length; j++)
                {
                    if (a[i] == b[j])
                    {
                        c = 1;

                    }
                    else
                    {
                        if (c == 1)
                            d = 0;
                        else
                            d = 1;
                    }
                }
                if (c == 1) { Console.WriteLine(a[i]); d = 0; }
                if (d == 1) { Console.WriteLine(0); }

            }
            Console.ReadKey();
                }

While
using System.Linq;
you can do this:
var result = string.Join(",", arrayA.Select(x => arrayB.Contains(x) ? x : 0));
there ya go ;)
