Can you provide a code to find a string in lexicographic order which is in between given two strings and the other steps required given the following:
Find a string in lexicographic order which is in between given two strings | Function to find the lexicographically next string.
Iterate from last character.
If not ' z ' , increase by one.
if ' z ' , change it to 'a.
Driver Code.
If not equal , print the resultant string"

#Here is code to find a string in lexicographic order which is in between given two strings and the other steps required.
 def lexNext ( s , n ) :
	for i in range ( n - 1 , - 1 , - 1 ) :
		if s [ i ] != ' z ' :
			k = ord ( s [ i ] )
			s [ i ] = chr ( k + 1 )
			return ' ' . join ( s )
'
	s [ i ] = ' a '
if __name__ == " _ _ main _ _ " :
	S = " abcdeg "
	T = " abcfgh "
	n = len ( S )
	S = list ( S )
	res = lexNext ( S , n )
	if res != T :
		print ( res )
	else :
		print ( - 1 )
