 int c, first, last, middle, n, search, array[]; 

 Scanner in = new Scanner(System.in); 

 System.out.println("Enter number of elements"); 

 n = in.nextInt();  

 array = new int[n]; 

 System.out.println("Enter " + n + " integers"); 

 for (c = 0; c < n; c++) 

 array[c] = in.nextInt(); 

 System.out.println("Enter value to find"); 

 search = in.nextInt(); 

 first = 0; 

 last = n - 1; 

 middle = (first + last)/2; 

 while( first <= last ) 

 { 

 if ( array[middle] < search ) 

 first = middle + 1;  

 else if ( array[middle] == search )  

 { 

 System.out.println(search + " found at location " + (middle + 1) + ".");  break; 

 } 

 else 

 last = middle - 1; 

 middle = (first + last)/2; 

 } 

 if ( first > last ) 

 System.out.println(search + " is not present in the list.\n");
