I've been mentoring students and professionals for over a decade.

Based on this experience, I've created an (almost) exhaustive list of the most impactful rules & concepts.

Make 2024 your best year: 👇

@Param3021 Looks like Skewb to me

[Abhishek Verma 💻 @intelocode]

@anonthedev @pickover just occupied with too many things,
didn't find time for sm

Irony: social media influencers mocking a kid with dreams.
Not even an original mocking, copied from elsewhere😅

Only someone with an "aim", has the possibility to achieve it. So, probably he or someone like him.

For anyone trying to pull him down, why not first reply with the IIT you graduated from.

@pickover We can choose 1 of the 3 horizontal lines and 2 of the 4 lines meeting top vertex.

So number of triangles
= ³C₁ * ⁴C₂
= 3 * 6
= 18 ✅

@edit_tweets Happy Birthday, Aditya !🎉

@USMoose1 @pickover Circle is an ellipse.

[Abhishek Verma 💻 @intelocode]

@pickover The complexity of this problem is surely being underestimated.

For those interested in the answer,
its possible but numbers are huge.

@pickover With 4 colors

[Abhishek Verma 💻 @intelocode]

@Labgo @pickover One region was lost due to symmetry.

If you move any one point on circle slightly, you'll find 1 more region emerge in the center.

Hence, resulting in 31 regions.

[Abhishek Verma 💻 @intelocode]

@pickover It would be 31 ✅

The series that forms is:
1, 2, 4, 8, 16, 31, 57, 99, 163, 256, ...

It can be derived using ⁿC₄ + ⁿC₂ + 1 ☑️

If wondering why it appeared like 2ⁿ for initial terms, the answer lies in the Pascal's triangle:

[Abhishek Verma 💻 @intelocode]

The coefficients are the numbers in Pascal's triangle (which is extremely easy to create). In any row, just add the two adjacent values and it gives the value below.

This allows to skip the tedious calculation and find next expansion just by using the current one.

@sainagateja_24 That's correct ! 💯

[Abhishek Verma 💻 @intelocode]

An interesting way to check if the given alphabet is vowel using bit manipulation.

Have a look if you understand how it works !

[Abhishek Verma 💻 @intelocode]

@_fels1 @kijogi Penguins live don't live on the north pole.

Just an FYI.

[Abhishek Verma 💻 @intelocode]

@ajoykdas Happy new year to you too !

[Abhishek Verma 💻 @intelocode]

@pickover @gs_bangalore There are 9 rows and 9 columns, so total rectangles
= Σ9 * Σ9
= 45 * 45
= 2025 ✅

Explanation:

Out of 9 rectangles in rows (or columns), "k" continuous rectangles can be selected in "10-k" ways (k ∈ [1,9]).

Hence, resulting in 1+2+...+9 = Σ9 ways to select from rows/cols.

[Abhishek Verma 💻 @intelocode]

@horsemankukka Right, glad that you mentioned.

Initially, I wrote "such year had never occurred for 4 digit years", then while rephrasing/editing seem to have missed that part.

[Abhishek Verma 💻 @intelocode]

Happy New Year, 2025 ! 🥳🎉✨

May this year bring you joy, prosperity and everything you wish for !

Numerically, year 2025 holds rare gems which won't occur for decades and centuries. Let's explore 🧵👇

[Abhishek Verma 💻 @intelocode]

@sainagateja_24 Happy new year to you too !

[Abhishek Verma 💻 @intelocode]

@Ali6nX404 Happy new year, Mahesh 🎉

[Abhishek Verma 💻 @intelocode]

@Ali6nX404 Agree, tbh I felt same 😅
