Synopsis:

There are a couple different ways to design an app but most are centered around the way the data is stored and accessed. This is the reason why going from a one-directional marketplace to a bi-directional marketplace was difficult: everything built "on top" of the data had to change as well.

Goals

Streamline our development and product planning processes.

Goal 1 - finalize data model based on our desired functionality

Find the odd ball out

8 ball problem

Of 8 balls one of them is a different weight. The only way to find the different ball is to use a scale. Find the odd ball (no pun intended) and determine if it's heavier or lighter than the rest.

Solution summary

Use a decision tree to deduce what balls need to be removed.

Max number of weighings: 3 #####Notes:

  • Finding normal balls for reference in the 2 ball series is trivial so I won't reference finding them.
  • Numbers in an array represent balls on one side of a scale like "[1, 2, 3]".
