🪕 "When a person can't find a deep sense of meaning, they distract themselves with pleasure." - Viktor Frankl

Something that interested me this week

This past weekend we had a small online conference with my Patreon Discord channel! It was a blast, a bunch of people in the group gave really interesting talks on things like ray tracing, design, functional programming, podcasting, cryptocurrency, and more! I’ll be sure to upload the talks soon.

Also, I’m sure you’re hearing it everywhere, but I’m going to say it again: please stay home, and wear your masks when you go out. Together we can slow down the spread of the virus.

This week’s sponsor is Studio 3T!

Interview question of the week

Last week, I had you generate a number of playlists. This was a toughie! Great job Roman, Pozorvlak, Ten, and Sameer!

This week’s question:
Given an array of integers arr, a pair (n,m) is called “special” if arr[n] == arr[m], and n < m. Return the number of special pairs. Hint: Nested for loops can work for this one, but a hashmap solution will have a better runtime!

Examples:

$ specialPairs([1,2,3,1,1,3])
$ 4 // (0,3), (0,4), (3,4), (2,5)

Joke

Did you hear about the actor who fell through the floorboards?
They were just going through a stage.

That’s all for now, folks! Have a great week. Be safe, make good choices, and stay indoors!
