Question

Define a class pin code and store the given pin codes in a single-dimensional array. Sort these pin codes in ascending order using the Selection Sort technique only. Display the sorted array.

110061, 110001, 110029, 110023, 110055, 110006, 110019, 110033

Answer 1

class SelectionSort
{
   public static void main(String args[]) 
   {
     int arr[]={110061,110001,110029,110023,110055,110006,110019, 110033}; 
     int len=arr.length
     //performing selection sort in ascending order
     for(int i=0;i<len-1;i++)
     {
        int pos=i;
        for(int j=i+1;j<len;j++)
        {
        if(arr[pos]>arr[j]) //finding the smallest element
     w.r.t. index pos. i
         pos=j; 
        }
        int temp=arr[i]; //swapping using 3rd variable
        arr[i]=arr[pos];
        arr[pos]=temp;
     }
     System.out.println("Array elements after the 
     sorting"); 
     for(int i=0;i<len;i++)
     {
        System.out.print(arr[i]+" ");
     }
   }
}

Output:

Array elements after the sorting

110001 110006 110019 110023 110029 110033 110055 110061
