hashmaps are O(n) worst case but y'all aren't ready to talk about that

¿Sabes cómo sumar datos numéricos de un HashMap Java?

¿No? Pues déjame ayudarte. Una de las tareas más repetitivas es realizar operaciones matem��ticas sobre datos numéricos que se encuentran en una estructura de datos y, algo sumamente frecuente es que esa estructura sea un HashMap en Java.

Te ofrezco varias soluciones para que puedas ver cómo podemos operar sin y con uso de bucles:

Leetcode

Did some leetcode problems and I encountered the fabled hashmap. I"ve been lurking a bunch of subreddits on career things, and I keep encountering "just do a hashmap". "If you don't know how to solve a problem, just say you should do a hashmap" I'm not sure how much of this is a meme. I learned it in my comp sci classes a while back, but I've been off doing other things and I'm reviewing concepts right now.

Also learned about enumerate() in the meantime. It's a handy way of keeping the index in python during a for loop, instead of using range or a counter.

It's helpful

oh yay they added something like lazy_static to the rust standard library that's really nice

I've been practicing data structure problems, mostly array based questions. I thought binary search was easy but i found it quite hard to implement in certain problems.

rustlings exercise hashmaps3 you are my worst fucking enemy

. i have to do long division and not just use a calculator for the hashmap modus. calculator just gives a decimal, not the remainder.

these two gifs always entrance me.. the ways she physically picks the card like it is a leaf on a tree, and that makes it just Turn Into the item. like this is a physical thing in space she is interacting with

and then the way the cord stays attached across the two cards with the hub and the laptop like that as they both move around. so fucking cool to me i love early homestuck i love sylladex shit

How is PHP not a conlang. Wdym that the only datastructure is a hashmap?!?!?? Php is what you get if you go "wouldn't it be fucked up if everything was a hashmap". You need an object? That is basicly just a hashmap with associated functions.

And the worst part is that hashing is it's whole deal but if you want to hash by a touple it's like, a tuple? you mean an array(hashmap again)? well of course we can't hash that.
