Can you provide a code to lexicographically smallest subsequence possible by removing a character from given string and the other steps required given the following:
Lexicographically smallest subsequence possible by removing a character from given string | Function to find the lexicographically smallest subsequence of length N - 1.
Generate all subsequence of length N - 1.
Store main value of string str.
Erasing element at position i.
Sort the vector.
Print first element of vector.
Driver Code.

#Here is code to lexicographically smallest subsequence possible by removing a character from given string and the other steps required.
 def firstSubsequence ( s ) :
	allsubseq = [ ]
	k = [ ]
	for i in range ( len ( s ) ) :
		k = [ i for i in s ]
		del k [ i ]
		allsubseq . append ( " " . join ( k ) )
	allsubseq = sorted ( allsubseq )
	print ( allsubseq [ 0 ] )
if __name__ == ' _ _ main _ _ ' :
	S = " geeksforgeeks "
	firstSubsequence ( S )
