Fenwick Trees are Awesome!

This post will only use one-based indexing since that’s what Fenwick trees traditionally use, although they can also be modified to use zero-based indexing.

So imagine you have an array $A$ of size $N$, and you’d like to support two operations. The first one, called $Update(i, v)$, is trivial: Given an index $i$, add $v$ to $A_i$. Easy peasy!

Asian Bayesian 2

I saw a really cool probability problem posted by Kartik Chandra on the MIT Mastodon instance:

Suppose two Bayesians, Alice and Bob, decide to put on a variety show where they take turns tossing a biased coin and announcing outcomes to a live studio audience. (Bayesians love this kind of thing–it keeps them entertained for hours…)

Recently, I noticed that “Bayesian”, as in Bayesian statistics or Bayesian inference, sounds very close to “Asian”. Pun potential!

“I prefer Bayesian models over Asian models.”
