Binary search of a sorted array

Question

I am trying to search a descending sorted array using this binary search code. However, after I sort it, and try to search, it doesn\'t come back with any result, just a loading

Answer 1

Its worked for me

public static int search(int[] arr, int value)
{
    Debug.Assert(arr.Length>0);
    var left = 0;
    var right = arr.Length - 1;

    while (((right - left)/2) > 0)
    {
        var middle = left + (right - left)/2;
        if (arr[middle] < value)
            left = middle + 1;
        else
            right = middle;
    }
    return arr[left] >= value ? left : right;
}
