This video will change the way you think when coding

"How to learn coding efficiently", this is a question that haunts many self taught programmers. In this video, I will answer this question and some others. For example:
1. How to become better at Programming?
2. How to actually make progress when learning to code?
3. How to become a Software Engineer?

For those who didn't explain the bat and ball example ( don't forget he works at Google, so at his level this is like ABC thing for him, so he assumed it makes sense to all of us 😅): bat + ball = 1.1 since bat costs 1 dollar more than a ball, lets assume ball costs x amount, so cost of a bat is ( 1$ + x ), so if we fill in the cost of bat in the equation: (1+x) + x = 1.1 (we replaced ball with x, because we assumed x to be the cost of the ball) 2x = 1.1 - 1 2x = 0.1 x = 0.1 / 2 x = 0.5 hence, ball = 0.5

bat + ball = $1.10 => - $1 => $0.10 / 2 => ¢0.05. I have a problem with my algorithmic thinking 🥲 When they give us a more complex task with a one-page description (at university) I just switch off and don't know where to start. I know that with practice everything will be fine, but now it's very demotivating especially since most handle these tasks 😤Greetings from Bulgaria 🙂

[@keentoknowher]

Hi greetings from India, why it's getting divided by 2

[@emil_petkov_py]

$1.10 - the price of the ball = the price of the ball + $1.00 If we rearrange the equation, we get: 2 * the price of the ball = $1.10 - $1.00 2 * the price of the ball = $0.10 If we divide both sides by 2, we get: the price of the ball = $0.10 / 2 = $0.05 Then the price of the bat equals the price of the ball + $1.00, or $0.05 + $1.00, which equals $1.05. So, in the end, the bat costs $1.05, and the ball costs $0.05, and together they are $1.10, as stated in the initial data.

What if your currency has 1c and 2c pieces….? The Bat and Ball question makes an assumption which is what I see trips up a LOT of programmers. If you want to break the ‘technical rules’ of a programming system then you’re going to have to learn to transcend the limitations of many of the assumption’s/interpretations of those rules your own mind may ‘incorrectly’ be imposing on the question/problem - not the rules themselves.

[@germantoenglish898]

Dinesh always makes me smile! 😃👍 Great video, really helped me see my false thinking concerning programming. A similar weird thing happened with scientists watching zebras. They couldn't figure out why they didn't have a better camouflage. Why were they so black and white, why didn't nature make them a colour to blend in the landscape. But they quickly found out that they themselves had problems telling the zebras apart. So they put a stripe of red paint on the animals to distinguish them. This was a bad idea, because it helped the lions too and these marked animals were quickly killed and eaten. Sometimes hiding in plain sight is best. 😂

If you want to learn Web Development then learn JavaScript or if you want to learn App Development or Backend only then Java is also a good choice. And don't waste time choosing a language pick one learn it along with DSA then make some projects and also practice DSA questions too. Switching to another language is easy if you have already learnt any language in full details

I know the logic and idea but while implementing the logic, I face problems. I can't implement that logic in my code. What should I do? Can u please help me, sir?? Love from Nepal🇳🇵

[@bencebukovecz8665]

I would say then your logic isnt fitting to solve the problem after all and / or you missing something. It could be that you havent wrote enought code yet to implement that specific logic and you are missing the tools to achive that. Try to indentify following: does my code have syntax issues or a typo if no , and your code works fine and still doesn't produce the expected results, it might be time to reconsider your initial logic. Try to use your set of "tools" to develop your logic and later you can always refactor. Usually what helps me that i get my rubber duck (Rubber duck method) then I go inside of the debugger and line by line look at how my function / application works.

My explanation is in detail if I have made some mistakes do mention I correct it. Now just remember the price which is 1.10 and according to the question whatever the price of the ball is the bat price will be 1 dollar more? Example: if the ball costs 1 dollar then the price of the bat will be 2 dollars as we have to add the BallPrice+1(as the bat price will be 1 dollar more) i.e 1+1=2(BatPrice) Now for the given question, the bat+ball= 1.10 dollars and what is BallPrice=? So, using the logic above as rough the BallPrice=.05 cent and the BatPrice=BallPrice(.05)+1=1.05 Now adding both the prices i.e. BallPrice(.05)+BatPrice(1.05)= 1.10 dollars Now to get the price of the ball you can now easily understand the explanation of @Explore The Internet. N (BallPrice) N+1 (BatPrice) i.e BallPrice + 1(from the question as Bat price is 1 dollar more) if N = 2 (BallPrice) then N+1 = 2+1 = 3 (BatPrice) Now according to the question N (BallPrice) + N+1 (BatPrice) = $ 1.10 To get the ball price N+N+1 = 1.10 [N+N = 2N] 2N+1 = 1.10 2N = 1.10 - 1 (if we send +ve sign number from LHS to RHS it will get subtracted and Vice Versa) 2N = 0.10 N= 0.10 ÷ 2 ( here it will get divided when sent to RHS as it is the only remaining number in LHS if anyone who has studied maths in class 4th and 5th they can understand what I am saying here) N = 0.05 is the ball price.
