Alternative Big O Notation

I always found things easy to remember when they rhyme, especially with humor. So, here is my take on big O notation, which can help you remember the rankings of big O types:

O(1) = O(yeah)
O(logn) = O(nice)
O(n) = O(k)
O(n^2) = O(my)
O(2^n) = O(no)
O(n!) = O(mg)
O(n^n) = O(sh*t!)

If you want to see my actual article explaining Big O time/space complexity types, here it is:

If you want to have the alternative Big O notation as a sticker, so you can stick it to unusual places, you can get it from quanticdev.com/shop.

If you really want to confuse fellow software engineers, you can also get it as a small poster, bigger poster, framed print, hoodie, phone case, mug, blanket, or even a shower curtain!

Side Note: Asymptotically, O(n^n) is equal to O(2^n), so the last line in the alternative big O notation list is just for the humor’s sake.


Did I forget to say that there is also a video version of this article (!)
