Lexicographically smallest subsequence possible by removing a character from given string | Function to find the lexicographically smallest subsequence of length N - 1.
Store index of character to be deleted.
Traverse the String.
If ith character > ( i + 1 ) th character then store it.
If any character found in non alphabetical order then remove it.
Otherwise remove last character.
Print the resultant subsequence.
