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

Shot in the dark:

if (target < mynumbers[mid]) 
   first = mid + 1; 
else if (target > mynumbers[mid]) 
   last = mid - 1; 
else 
{
    ....
    break;
}

I suspect you're bouncing back and forth between mid+1 and mid-1
