#Here is code to largest even digit number not greater than N and the other steps required.
 def checkDigits ( n ) :
	while ( n > 0 ) :
		if ( ( n % 10 ) % 2 ) :
			return False ;
		n = int ( n / 10 ) ;
	return True ;
def largestNumber ( n ) :
	for i in range ( n , - 1 , - 1 ) :
		if ( checkDigits ( i ) ) :
			return i ;
N = 23 ;
print ( largestNumber ( N ) ) ;
