Alice has to go to work from his home. He finds it somehow the first day and keeps a note of it . In the office she finds the path to be longer and shortens it.

Given a string of the long path, shorten it. The result must be sorted lexicographically .

Example : SSNE to be simplified as ES

S stands for South, N for North, W for west , E for east.

What I have tried:

I'am thinking to delete all the same characters which occur together and keep only one of them.

eg:
SSSNNEW -> SNEW -> ENSW(Answer)

and later sort the string lexographically. Is it the right way ??

Wrong
the principle is that N and S are opposite directions, same for E and W.
It means that if you have both; a move S will cancel a move N, same with E and W.
So SSSNNEW -> SSNEW -> SEW -> S

we can solve this problem using a stack if stack is empty push to the stack

always compare stack top with the current element in the string.

if top is S and element is S then push S. Similarly for N, E and W.

if top is S and element is N or vice versa then pop from stack and don't push.
if top is W and element is E or vice versa then pop from stack and don't push.

then pop all elements which are remaining in the stack and store that in a string ans sort the string and print the string.

You are a bit late to the party, aren't you?

Solution 1

No. Look at the example:

SSNE -> ES

What you need to do is remove opposites: A North and a South pair, and East and West pair. When you have removed pairs, you can sort.
