The thing about finding new patterns when you hit a wall is so true. I used to have trouble solving certain problems and then I found out about dictionaries and tuples. I was able to solve so many more after it. Need to find more patterns again. Thank you!

@aldoaguirre9864 8 ай бұрын

thank you so much for this!

@haha-eg8fj 6 ай бұрын

to be able to spot the patterns you need to be exposed to a large dataset, which means you have to solve enough problems to gain that knowledge. And that is far from enough because if you do it slightly differently than the optimized solution there will be tons of edge cases to be considered.

Can someone solve this for me? In the army of Andromeda, the soldiers are segregated by rank. Each soldier except the first has a superior officer. The codes for the nuke are given to 2 soldiers for security purposes, and each would relay the information to their superior officer (this keeps on happening till it reaches the top most officer). The first officer who gets the information from two of his subordinates would detonate the nuke. Given m such queries find the officer who would detonate the nuke for each of them Input Format First line has an integer n,m, for the number of soldiers and number of queries. Second line has n−1 integers p2,p3,p4 … pn where pi is the superior officer of officer i. Next m lines have 2 integers a and b, such that the codes are given to soldiers a and b. Constraints 1

Here the trick part is "the bat cost 1 dollar more than the ball" Which means, the ball cost is also there in the bat plus 1 dollar.. so if the ball cost $0.10 then the bat would cost $1.10 and total would be $1.20 dollars which is not the right answer.

took me some thinking between both fast and slow brain to get to a bat costing $1.05 and a ball costing $0.05. When solving things with the fast brain, sometimes it takes one on a journey with their slow brain to make sure they got it right only to find oneself doubting self and repeat checking with the slow brain; only to confuse oneself! At least, that's what I experience when I try to do things my fast brain does with the slow brain!

To people like me : Let the cost of the ball be "B" in dollars. According to the information given, the bat costs $1 more than the ball, so the cost of the bat would be "B + $1." Now, we know that together, the bat and the ball cost $1.10. So, we can set up an equation: B + (B + $1) = $1.10 Combining like terms: 2B + $1 = $1.10 Subtract $1 from both sides of the equation: 2B = $0.10 Now, divide by 2: B = $0.10 / 2 = $0.05 So, the cost of the ball is $0.05 or 5 cents.

I just want people to understand, that to some people things WILL come more naturally than it will to others. And for a lot of people, no amount of hardwork will make you as good as the people to who it comes naturally. The faster you understand that and stop guilt tripping yourself, the better it will be for you and for your health. It doesn't make you worthless, it's just that you'll be useful in different roles than those people. And you can still do you part, but there might be somebody who'll be able to do the things you do faster, and in a way that you may never conceive. And you cannot learn that. The fast you realise that, the better it will be for you. Anybody that tells you that hardwork will make you as good as the person that it comes naturally to, is lying to you The only person you should compare yourself to is you. You can become better than you were. You can even be more productive than the genius. You can even produce better work than the genius, but you're not gonna be able to train yourself to become better at coming up with things that comes naturally to them.

@charankoganti5764 8 ай бұрын

Well, rather than directly jumping to coding by yourself, analyze different codes for different problems that are available on different platforms. Make sure that you try to analyze why they have done a particular line of code that way. Do this for at least 15-20 days, by this way you'll build your confidence and you know the tricks as you have analyzed different codes. Taking your time is the key! Hope it helps. All the best!

The problem states that sum of bat price and ball price is $1.10. Also, cost of bat price is 1 dollar more than that of ball price. Find the ball price. Let ball price be x; Bat price = 1 + x; Bat price + ball price = $1.10 (given) //putting values (1 + x) + x = 1.10; 2x = 1.10 - 1 = 0.10; x = 0.10/2 = 0.05; Hence ball price is 5 cent. Hope you got it 😇
