Programming, Software, and Technical Interview Questions - XOR Swap How to think like a programmer — lessons in problem solving by Richard Reis If you’re interested in programming, you may well have seen this quote before: “Everyone in this country should learn to program a computer, because it teaches you to think.” — Steve Jobs You probably also wondered what does it mean, exactly, to think like a programmer? Essentially, it’s all about a more effective way for problem solving. In this post, my goal is to teach you that way. By the end of it, you’ll know exactly what steps to take to be a better problem-solver. Why is this important? Problem solving is the meta-skill. We all have problems. Unless you have a system, this is probably how you “solve” problems (which is what I did when I started coding): Try a solution.If that doesn’t work, try another one.If that doesn’t work, repeat step 2 until you luck out. Look, sometimes you luck out. The best way involves a) having a framework and b) practicing it. “Almost all employers prioritize problem-solving skills first. Have a framework Soon, you too will know them. 1. 2. 3. 4.
Coding from college to high school | Schools It’s not often that a high school elective class can make students immediately employable. Jenny Barnes, John Notestine along with Colony High Teacher Brian Mead are bringing a surplus of job opportunities to students. It’s called CS50, and the plan is to have it be the most popular class in school. CS50 stands for Computer Science 50. It’s a MOOC, massive open online course, started at Harvard by Professor David Malan. At Harvard, the class became so popular and well-loved that Harvard decided to take it on the road, teaching coding to high school students. The high school version of CS50 takes the semester long university course and extends it over an entire school year. “It’s not just because we want kids to have jobs; it’s because we need people to do these jobs,” Barnes said. Even though Barnes and Notestine are both equally excited to teach CS50, it is hard to match the enthusiasm for CS50 like Colony High’s Brian Mead. But coding is only one component taught when it comes to CS50.
uzun ekran görüntüsü alma Let's Code Better - Algo Muse 16-1 In the box There are n identical boxes in which 2n balls are equally distributed. The balls are labelled from 1 to 2n. We don't know which ball is in which box, but do know that each box contains two balls. The objective is to learn the arrangement of balls. For any set of balls S ⊆ {1,...,2n} we can ask a query of the form `How many boxes contain the balls in S?'. Prove that we can learn the distribution of balls by asking O(n log n) queries. Note that we cannot tell which ball is in which box. Solution Solution There are n pairs of balls. Lemma. Proof. How many boxes contain the balls in set A? If answers to both the questions are same, then x is paired with one of the balls in set A; else x is paired with one of the balls in set B. 16-2 Evasive Tree We prove the lower bound for the special case when the tree is a path, using an adversarial argument. Assume that the algorithm never asks a query to which it can infer the answer. Analysis. 16-3 Saving a log
Rubber duck debugging From Wikipedia, the free encyclopedia Code debugging method In software engineering, rubber duck debugging (or rubberducking) is a method of debugging code by articulating a problem in spoken or written natural language. The name is a reference to a story in the book The Pragmatic Programmer in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it, line-by-line, to the duck.[1] Many other terms exist for this technique, often involving different (usually) inanimate objects, or pets such as a dog or a cat. Teddy bears are also widely used. Many programmers have had the experience of explaining a problem to someone else, possibly even to someone who knows nothing about programming, and then hitting upon the solution in the process of explaining the problem.

My journey to becoming a web developer from scratch without a CS degree, 2 years later (and what I… My journey to becoming a web developer from scratch without a CS degree, 2 years later (and what I learned from it) First, let me introduce myself; My name is Sergei Garcia, and I’m a full-time front end developer with 2 years experience, and in that time having worked for both a Forbes 500 Consulting Firm and Small Company as a Front End Developer. This may not be a lot of many, but for me it’s quite a big milestone since 2 years ago, I had little to no real programming experience in web development (or programming in general, I only had some basic C# and Java training I got from a few online courses), or a Computer Science degree since I graduated with a degree in IT project management. It’s come to my attention that I’ve never written about this or my experience despite all the help I’ve received from wonderful communities like Medium, Stack Overflow, and Reddit’s programming subreddits. So, without any further ado, Let’s get started! Getting the Basics And this is how it went; AngularJS
