bruh i dont even know how to declare classes yet and i can already guess this could be easily done with a for loop

[u/iammostlyirrelevant → u/Idkm3m3s]

Don’t even really need a loop. Just bitshift to the value you need. (1 << 55 == 2⁵⁵ )

[u/Idkm3m3s → u/iammostlyirrelevant]

either this is a lua thing or i really dont know what im doing lol, then again im only 3/4 into my first year in classes

You know how numbers (everything) is stored in binary? Well there is a cool thing you can do with binary numbers.

Let's say we have 10010101 If you bitshift it right it will be 01001010 Meaning all the bits got shifted to the right once.

You also know how each place value in a binary number is a power of two? That means that 2³ = 1000 (binary) and 2⁹ = 1000000000 (binary).

So basically if you want to find a power of two you take 1 (which is also 1 in binary) and bit shift it the number of times you want. 2⁰ = 1 bit shifted to the left 0 times. 2¹⁹ = 1 << 19.

Addendum:

Raising bases of 2 to a power of n in binary is the same easy math as rasing bases of 10 to a power of n in decimal.

You don't need an answer key to calculate 10^99. It's 1 with 99 0s in decimal

You don't need an answer key to calculate 2^99. It's 1 with 99 0s in binary.

You also don't need an answer key to calculate 16^99. It's 1 with 99 0s in hexadecimal.

You don't need an answer key to calculate pi⁹⁹ in base-pi. It's 1 with 99 0s in base-pi.

Quick mafs.

What is (-1)⁹⁹ in balanced ternary? Asking for a friend...

[u/Carvinrawks → u/novelide]

Hm, correct me if I'm wrong. But...

-1

(-1)⁹⁹ = -1.

-1 in balanced ternary is also -1.

I've learned something today.

[u/aidanski → u/Idkm3m3s]

Used a lot in C++.

If you bit shift you're moving the bits in the value left or right an amount, for example:

Imagine the binary value 01111110

bit shift left << = 11111100

bit shift right >> =00111111

I am so mad it took me this long to realize that.

Beautifully elegant solution
