Windows services, previously known as NT services, are applications that are installed on the system as system services. In other words, Windows services are applications that run in the background with the Windows operating system. The primary use of Windows services is to reduce the consumption of memory required for performing backend operations. Let's take an example to understand this easily. Suppose you want to perform a variety of functions, such as monitor the performance of your computer or application, check the status of an application, and manage various devices, such as printers.

In such a case, you can use Windows services to reduce memory consumption. In addition, Windows services can run on your system even if you have not logged on to your computer. In addition, these services do not have any user interface.

1. Have two indexes pointing to two ends of array, say i and j.

2. Approach towards each other with a check condition that they dont cross each other.

3. Each iteration of while loop, swap the numbers pointed by two indexes when num[i] index number is not equal to 1.

void sort()

{

     int a[]={1,0,0,0,1,1,0,1,0,1,0,0,1,0};

     int i=0;

     int j=13;

     int temp;

      while(j>i)

     {

          if(a[i]==1)

                 i++;

          if(a[j]==0)

                 j--;

          if(a[i]==0)

         {

                 temp=a[i];

                a[i]=a[j];

                a[j]=temp;

         }

     } 

     for(i=0;i<14;i++)

             Console.Write(a[i]+", ");

}

Output: 1,1,1,1,1,1,0,0,0,0,0,0,0
