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

iankiku / the % notation in ruby.md
Created January 26, 2023 07:51 — forked from jakimowicz/the % notation in ruby.md
%Q, %q, %W, %w, %x, %r, %s, %I, %i

%Q, %q, %W, %w, %x, %r, %s, %i

Perl-inspired notation to quote strings: by using % (percent character) and specifying a delimiting character.

Any single non-alpha-numeric character can be used as the delimiter, %[including these], %?or these?, %~or even these things~.

Strings

% or %Q

How to regenerate the master key for Rails 5.2 credentials

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

  1. Copy content of original credentials rails credentials:show somewhere temporarily.
  2. Remove config/master.key and config/credentials.yml.enc
  3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
  4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
  5. Add and Commit the file config/credentials.yml.enc
