Abstraction of Binary Search | ''Function to find X such that it is less than the target value and function is f(x) = x ^ 2.
'' Initialise start and end.
'' Loop till start <= end.
'' Find the mid.
'' Check for the left half.
Store the result.
Reinitialize the start point.
'' Check for the right half.
'' Print maximum value of x  such that x ^ 2 is less than the  targetValue.
''Driver Code.
'' Given targetValue;.
'' Function Call"
How can the above be solved in Python?
 Give me a code to abstraction of Binary Search and the other steps required?

#Here is code to abstraction of Binary Search and the other steps required.
 def findX ( targetValue ) :
	start = 0 ;

	mid = 0 ;
	while ( start <= end ) :
		mid = start + ( end - start ) // 2 ;
		if ( mid * mid <= targetValue ) :
			result = mid
			start = mid + 1 ;
		else :
			end = mid - 1 ;
	print ( result ) ;
if __name__ == ' _ _ main _ _ ' :
	targetValue = 81 ;
	findX ( targetValue ) ;
