It’s because through metaphors, concepts are more accessible, digestible, and easy to remember. Thank you for your posting! You can solve this through recursion!” in your head. “A variable is like a named box where you can put information in.” Before all the technical geeks jump on my throat, please bear with me, at least past the “Exploration” section (then I’ll have a 200 yard headstart, just kidding). an easy way to learn Computer Basics, Programming, Fundamental, Hardware, Software, General Knowledge, IT related, Networking, Repairing and Advanced concepts from this app. First you have to catch a Pokemon. Wat language u recommend i begin with. There are so many more questions to ask about the metaphor of boxes to describe variables. The training wheels that were once a safety net are now gone and it creates a sense of frustration and loss. Does it store both items? Nothing would have prompted anyone (inexperienced) to add everything up and subtract 5050 from that. Ask them to voice their thoughts out loud. I’m a novice to computer science and I really enjoyed your article for two reasons. Exploration is done with the aim of identifying their strengths and weaknesses to present an informed and advanced critique. Ask a Peer 4. It’s like playing God. Q: If you are given 100 tiles numbered from 1 to 100, shuffled in a bag, with 1 duplicate number in the bag that’s between 1 and 100 (giving you 101 numbers), how do you find the duplicate number efficiently? Having a stepping stone, a less ideal solution, is crucial to reaching your final destination. Your post helped me a lot because it motivated me a lot. It might make sense to the average computer scientist, but to a novice, it means NOTHING. However, over a period of time, this device technically advanced; at present, it can perform a wide range of desirable works apart from data processing. Basic Knowledge of Computer – Main Parts of Computer Barcode reader. Being friends is important, but don’t let it become distracting when you guys have to study or work together. And how does it decide where to store it?”, Friend: “Well, when the compiler of the program runs, it creates a memory address in the memory. In a similar fashion, the variance of the y distance per second is also ½. 80% of the time you can easily test it out. It’s better to find someone who has a poorer mastery of a subject who can explain his understanding clearly than it is to find someone who is a computer genius who would just scoff at your dumb questions. Good programmers get themselves out of these trenches. —–[ ]—-[ ]—-[ ]————-[ ]—–, ——–[ ]—————, ——–[ ]—-[ ]—[ ]———————-. Whatever you’re learning, try to find a convenient way to be able to write and test code. Find X). You’ll have trouble remembering the context of the problem, the nature of which the problem is constructed, what you do or don’t understand, and naturally, you’ll lack a complete understanding of the solution. Let me demonstrate what this means through an example. We would have never arrived at the answer nor know there was a possible solution from the outset. If you want to extend your box analogy, just imagine a stack of boxes. How are errors in my code handled? The first is finding personal projects. You need someone’s help. How to Find Answers 1. It is very hard to see the perfect solution from the get go. I broke each interval down into four cases, and handled each case separately. If we say that “=” means putting a thing in another box, by metaphor, “=” means “put box B in box A.” See what happens when you print a, does it print out “B,” “1,” “2,” or “ERROR”? Often, you’ll find a wide and supporting community (although never paramount to person-to-person meetings). If the woman had daughters of any other age, her telling the sum would NOT have stumped the census taker, but those two possibilities will. In 1822, he developed a machine capable to calculate the successive difference of expression and prepared a table which helped him in his calculations. answered by Mark Eichenlaub*, Cracking the Coding Interview by Gayle Laakmann, Harvard 1504: Positive Psychology by Tal Ben-Sharar (Used his concepts to write my conclusion), Fun Programming Challenges on ProjectEuler.net. Lovelace was an English mathematician, who researched on Babbage’s work. Done. What’s the difference between an int and a long?”, Friend: “One stores a 32-bit integer and one stores a 64 bit one.”, Friend: “It puts the value in a memory location.”, Friend: “The memory location is where the information is stored.”, Me: “That doesn’t help, where the memory location? If we find the duplicate, we stop. Well, we can’t be sure, and it doesn’t occur to many beginners that the answer is “YES!”. Make it second nature to recognize when a tool is useful. Deliberate Practice and Application 3. In 1947, John Mauchly and Eckart developed the first large scale Electronic Digital Computer. In computer science, particularly on tests and technical interviews, you are often asked to solve a problem quickly (uses less time) and efficiently (uses less memory). So our expected distance in the x direction is 0 in one sec, and our variance is ½ (Var(X) = E[X2]+E[X]2=½ +0=½). You can google it. Ok, ok. Learning a concept is like playing Pokemon. You poke you model a bit, see what happens. thanks! Let’s talk strategies. Simplification 1. So you draw a 10 by 10 square grid on your table, and for each tile you take out, you place exactly where the tile should be. Using Your Problem Solving Toolkit 2. Many people know how to Google, and the expertise comes with practice, or deliberate practice. Do you have the original item, or do you have the new one? Thanks. The first step is called visceralization. There are brackets that are inside the target interval, and there are the two edge brackets which we have to test to see if they are partly in the target interval.
