There is a binary search in the Array class:. The program then asks the user to input the search element (the number that needs to be searched in the list). public class ReverseComparer<T> : IComparer<T> { public int Compare(T x, T y) { return Comparer<T>.Default.Compare(y, x); } }. The function should return the index of the search key if the search key exists and return -1 if the search key doesn't exist. Here is a sample program to implement binary search in Java. The index of the specified value in the specified array, if value is found; otherwise, a negative number. Now ask to enter an element to search to start searching that element using binary search technique.
