Can you provide a code to maximum possible number with the given operation and the other steps required given the following:
Maximum possible number with the given operation | Function to return the maximum possible integer that can be obtained from the given integer after performing the given operations.
For every digit.
Digits greater than or equal to 5 need not to be changed as changing them will lead to a smaller number.
The resulting integer cannot have leading zero.
Driver code"
How can the above be solved in Python?

#Here is code to maximum possible number with the given operation and the other steps required.
 def maxInt ( string ) :
	string2 = " "
	for i in range ( 0 , len ( string ) ) :
		if ( string [ i ] < '5' ) :
			string2 += str ( ( ord ( '9' ) - ord ( string [ i ] ) ) )
		else :
			string2 += str ( string [ i ] )
	if ( string2 [ 0 ] == '0' ) :
		string2 [ 0 ] = '9'
	return string2
if __name__ == ' _ _ main _ _ ' :
	string = "42"
	print ( maxInt ( string ) )
