Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn-t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we-re going to take a look a couple modern computing problems like sorting and graph search, and show how we-ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell. or like a restaurant or something. Ps. Have you had the chance to play the Grace Hopper game we made in episode 12. Check it out here! CORRECTION: In the pseudocode for selection sort at 3: 09, this line: swap array items at index and smallest should be: swap array items at i and smallest

Please any one help. I am in 1st year 2nd semester going to finish. Now holidays due to Corona virus. I cant develop the logic of how to put the values properly and all. for eg like in pattern printing and most of the competitive problems like in codeforces and hackerank. My friends do simply all these. i dont know how to do it. What should I do. HELP. i dont know what And how to code.

At 10. 34 in the video what is the base of the log? Can't be 2 again?
Thanks in advance.
Edit: worked it out. Not really clear when talking about log base 2 earlier then just randomly jumping to log base 10 with no explanation. Also notation is not really clear. Some brackets would have been nice even though the bid as works.

6: 24 Umm, why is the log based on two, though? The O was n log n, isn't that n times log base 10 n?
Help, I'm stumped. She did say it had to do with the splitting, but I just couldn't cram the logic to my head without it hurting. Tasukete!

Algorithms aren't just about coding they are about the steps involved in solving a problem when you use a programming language to perform an algorithm then its coding.

That movie Interstellar is starting to make sense now, if everyone wants to be an engineer or computer major, w/o farmers the world would starve

I am writing an IT test tomorrow and I need help with algorithms and tracetables, but in words not with numbers. please----
