Can you provide a code to search an element in a reverse sorted array and the other steps required given the following:
Search an element in a reverse sorted array | Function to search if element X is present in reverse sorted array.
Store the first index of the subarray in which X lies.
Store the last index of the subarray in which X lies.
Store the middle index of the subarray.
Check if value at middle index of the subarray equal to X.
Element is found.
If X is smaller than the value at middle index of the subarray.
Search in right half of subarray.
Search in left half of subarray.
If X not found.

#Here is code to search an element in a reverse sorted array and the other steps required.
 def binarySearch ( arr , N , X ) :
	start = 0
	end = N
	while ( start <= end ) :
		mid = start + ( end - start ) // 2
		if ( X == arr [ mid ] ) :
			return mid
		elif ( X < arr [ mid ] ) :
			start = mid + 1
		else :
			end = mid - 1
	return - 1
if __name__ == ' _ _ main _ _ ' :
	arr = [ 5 , 4 , 3 , 2 , 1 ]
	N = len ( arr )
	X = 5
	print ( binarySearch ( arr , N , X ) )
