Hands-on Algorithmic Problem Solving

Creates Passion and Confidence from Mastering Algorithmic Problem Solving and Problem Patterns of Real Interview Questions

alt text alt text alt text Medium Blog

Purpose

The purpose of the book is to guide the reader's preparation to crack the coding interviews. Preparing for the coding interview, not easy! Cracking the coding interivew? Like impossible for most of us! Luck does play a slight role sometimes in the outcome. So, just treating it as a learning process. No matter what the result is, there will be no regret.

Computer Science is really not just computer science. It is a combination of all fields; our normal interview problems fall into the eumerative combinatorics and our computer vision mostly is related to Linear Algebra. What really matters is our passion about learning more and applying it to solve real-life problems. How about forgetting about cracking the coding interviews, and just simply enjoy a ride that trying to seek the soul of the programming world. I'm just like you, I love to learn and I love to write and try to do a better job. No matter how much time it takes, because I love learning it!

There are plenty of books out there focusing on either teaching algorithmic knowledge (Introduction to Algorithms, Algorithmic Problem Solving, etc) or introducing interview process and solving interview problems(Cracking the Coding Interview--seriously, you are not likely to crack any interviews with this book, haha!, Coding Interview Questions, etc), but barely any that combines the two. This is a book designed to make up this role in the categorization; learning the algorithmic problem solving by analyzing and practicing interview problems -- a reciprocal relationship that makes 1+1=4: Algorithms, Interviews, Passion, and Confidence.

This is NOT a book that provides hiring statistic of each company or gives the reader quick tricks in order to pass a few coding interviews(T'm not good with NLP, 'cause I'm a computer vision person). Its purpose is to show you the beauty of the algorithimc problem solving in the hope that you will be more passionate and condifent about software engineering; the interview questions just set up a play ground where we strengthen what we learn. A strong candidate would be apt to sleep well before interviews, walk into the interviews and discuss his or her findings about the question from all possible angles and program the best solution for on the white-board. The interviews shall be a setting the interviewers and interviewees both have a nice and happy talk; learning from each other instead of a one-way relation -- tester and testee.
