I was going through this editorial:
Only to encounter sentences like this:
we can easily supporting add new elements and deleting the element which is added most recently by using stack such that each element of the stack is the sequence of elements
Now, I totally understand that the author of the editorial may be a great programmer from a primarily non-English speaking country. It would be wrong of us to criticize him for having made grammatical errors when writing out the editorial, but Codechef grammar verifiers could at least understand that and give it a read and fix such blatant errors.
Not doing so results in Codechef users having to do a 2 step process:
Convert absurd English to proper English
Then understand the algorithm
It would be awesome if you could ensure the users only have to do step 2. It looks kind of unprofessional on your part to just post editorials without having such basic checks.
