QUESTION
I have been able to generate the all permutation of length 4 from a string, the problem that I am facing now is that all the permutation have duplicates like {abcd) ,{adbc},{bcda}...which are all same as from Mathematical definition of set.
Is there a short version in java-8 where I can get the pure set?
My code that generated the all permutation:
...ANSWER

QUESTION
i've looked and tried many solutions but for some reason I can't get it to work.
My goal:
- Automaticly sending e-mails on time trigger (works)
- Based on cell value (works)
- With HTML mail format (google form) (works)
- With 2 or more attachments (doesn't work)
How can I change the code so it'll include 2 pdf files? It can be one of the two options: 1. Grab pdf grom google drive folder by name, where I got a working function to export 2 or more sheets to pdf - using the same name (and removing older version). 2. Convert 2 or more sheets to corresponding PDF files and add them as attachment.
I'm rather new, so still trying to figure my way around.
Tried combinding Several solutions found here but I either keep getting 'file iteration' error.
When using variant of GetFilesByName, if(file.HasNext(), getAs('application/PDF'), I get no error but no mail is sent either.

QUESTION
Reverse indexing in python with the x[::-1]
format is very handy, but what is the logic of reversed indexing on slices? I understand that the idea is [high:low:-stride]
, but I find the following example confusing. In particular, why is it not possible to slice so that the entire iterable is reversed (without using the implicit [high::-1]
format)?
This Python 3.6 snippet:
...ANSWER
Answered 2018-Mar-09 at 00:26If i is 0, then s[6:(i - 1):-1]
becomes s[6:(-1):-1]
, since there are only 5 characters, you take all chars from the 6th place to the last place. And because there are no chars between those two you get an empty string.
If i is 0, then s[:i]
becomes s[0:0]
, since there are no charachters between 0 and 0, you get an empty string.
To print 'abcde' backwards, you use s[::-1]

This is homework and I need help understanding how and why.
I have tried to follow the numerous examples online, but they all hard code 'A' as the starting point, and I'm failing to reverse engineer the examples for my specific need.
