A Directory of Code Interview Questions

NOTE: THIS POST HAS BEEN DEPRECATED AS OF 11/22/20 … NO MORE UPDATES ARE EXPECTED ON THIS DIRECTORY….

This post will be the go to source for patterns, all of which will contain coding samples. If you’ve read Memorizing Code PART I, and Memorizing Code PART II, this is essentially “Part III” — or at least the “index” for all that follows. For convenient reference…

UPDATE: as of 11/08/2020
originally… the patterns I was writing about were focusing on employing a “cast of characters” to memorize code. After a few weeks, I’ve realized that its practicality is limited… However, personifying code IS helpful when trying to remember the basic premise of how a coding tool is expressed: for example slice versus splice (slice being temporary like a magical ninja doing magic tricks, whereas splice being permanent as in DNA splicing.)
