#Here is code to lexicographically largest sub and the other steps required.
 def getSubSeq ( s , n ) :
	res = " "
	cr = 0
	while ( cr < n ) :
		mx = s [ cr ]
		for i in range ( cr + 1 , n ) :
			mx = max ( mx , s [ i ] )
		lst = cr
		for i in range ( cr , n ) :
			if ( s [ i ] == mx ) :
				res += s [ i ]
				lst = i
		cr = lst + 1
	return res
if __name__ == ' _ _ main _ _ ' :
	s = " geeksforgeeks "
	n = len ( s )
	print ( getSubSeq ( s , n ) )
