Solves the InterviewCake.com problem that asks us to write a function that
returns the number, y, that occurs twice in a list, xs, where xs is an unsorted
list of integers from 1..n with a length of n + 1.
This is just a small org table that I created to help me
Fun fact: In Emacs, you can insert literal TAB character by pressing `C-q
TAB`. For creating tables, using TAB characters feels perfectly
acceptable. Perhaps the TAB name comes from TABle.
Solves an InterviewCake.com problem that returns the index of the element in a
list that should be the first element in that list. It's an exercise that's
useful for seeing other applications of a binary search.
Solves an InterviewCake.com problem that returns all of the permutations of a
string input. The problem states that it's acceptable to assume that your input
string will not have repeated characters, which is why using a Set is
acceptable. I like this solution because it builds a permutations tree and then
assembles all of the permutations by doing a DFT over that tree.
While I've done these algorithms before, I'm preparing for an on-site with
DeepMind, so I created a subdirectory called deepmind where I'm storing my
second attempts at these problems. The idea of storing them in a second
directory is to remove the urge to check my existing solutions that also exist
in this repository.
