Grokking the coding interview equivalent leetcode problems

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Python script for monitoring an IMAP folder
Each existing unread and subsequent new emails after the script is started are
passed as Mail objects to "process_email" function.Function header is provided
but processing implementation is left to the user. Error logs are currently sent
to a rotating log file (in the same directory as the script) and to STDOUT.
Instead of polling or checking the server for new emails every now and then,
IMAP IDLE check is utilized. Ensure that the IMAP server supports IDLE command
and allows at least 5 minutes of idling*** and uses the default ports for this
script to work. Tested to work with Gmail and default installations of MS
Exchange Server.
