BACKGROUND/PROBLEM PERSPECTIVE: After reviewing much of the available material on IBM’s Quantum and the general approach to Quantum computing, I felt somewhat conflicted. While I was able to watch the video with Dr. Talia Gershon, read about the 2019 Quantum Award Winners, and look through other featured Quantum news items, I was unable to reproduce … Read moreAnalysis of “Quantum Computing” as a Product
There are lots of lists I’ve seen on the internet, but in my opinion, this will be the best one yet, despite not having mini-pitches for any given book. All the books that appear on this list I have read personally and gotten much value from. And, while some are “better” than others, I believe … Read more41 Books for Product Managers in Tech, or Founders
As with many coding interview questions, the “usefulness” of a specific puzzle seems “useful” mostly in the context of getting a job. That said, if you need to use some data model to simulate some process in manufacturing, perhaps something where a “setup” requires a bunch of complicated bits and pieces to be entered “left … Read moreReversing a Linked List
This is a searching pattern that works best on pre-sorted data where you grab a midpoint value and would then determine whether the thing you’re looking for is of greater or lesser value. If you were dealing with a million numbers (or numerical IDs) then it could save you a lot of time. For example: … Read moreDivide and Conquer
So… this algorithm seems (at face value) rather pointless outside the context of a coding interview question. However, if you give it “a chance”, you’ll see that the Tortoise and Hare Pointer/Fast and Slow Pointer Pattern reveals the basic mechanic of identifying an Infinite Loop. While the example below does not account for what you … Read moreTortoise and Hare Pointers
Three Pointers is almost identical to “two pointers” except there is a third pointer (or “pincer”). This is useful for “three number sums”, or going with the ball factory example from the Two Pointer post, perhaps an item where three different balls are packaged together. A use case that I find fascinating might be K … Read moreThree Pointers
The code below is basically the same as the initial example used in the glossary, but doesn’t use reduce. For simpler memorization of the pattern, this example is better. As for the “What” and “Why” of Two Pointers, a frequent example would be some target value, and you need to iterate through some list/array to … Read moreTwo Pointers
