Write a Java program to search an element using binary search using array. Program: import java.util.*; public class Binary_Search { public static void main(String args[]) { int n, i, search, first, last, middle; int a[] = new int[50]; Scanner sc= new Scanner( System.in ); System.out.println("Enter the Number of Elements u want: "); n = sc.nextInt(); System.out.println("Note : please,Enter elements of an array either asending or desending order."); System.out.println("Enter " +n+ " Elements :"); for(i=0; i<n; i++) { a[i] = sc.nextInt(); } System.out.println("Enter a key value to Search:"); search = sc.nextInt(); //Binary search first = 0; last = n-1; middle = (first+last)/2; while(first <= last) { if(a[middle] < search) { first = middle+1; } else if(a[middle] == search) { System.out.println(search+ " Found at Location " +(middle+1)); break; } else { last = middle - 1; } middle = (first+last)/2; } if(first > last) ...
