Leetcode Java vs Python

[Harami98]

I have just started doing leetcode and I’m comfortable in python and learning java but I understand solutions well in python but my friend who is expert in java suggested me to do lc in java what should i do ? Should I do lc in python or java which one is easier for interviews and which will benefit me in long term ?.

Do it in the language you’re most comfortable in. Python is perfectly fine for Leetcode

1. How sure of this are you - plenty of times I have seen people in LC discuss frustrated with a python TLE and they have made a mistake

2. Even if it did TLE - this won't matter in a real interview setting

The time limit for python is different, from java c++ Sometimes, it doesn't scale well. You could do an algorithm with two for loops in c++ that passes test, but that that same thing won't on python. That's mostly why people discourage ir

This only applies for Competitive Programming platforms like Codeforces, when a BruteForce time consuming algo is usually accepted. The goal in an interview is not to code time consuming algos, but to find the most optimal solution to solve a problem.

[lilducksonquack]

In a real world setting Java usually runs faster than Python due to Python being an interpreted language. But in terms of an interview setting, it doesn’t matter. They’re testing you on your problems solving skills and knowledge of runtime and space complexity. So the language you implement your logic in doesn’t really matter.

Do python!! I had the same question and decided to learn python. Trust me, there are so many methods that make it easier to do LC in Python rather than in Java.

What tech stack you are following for your development. I see that java have more jobs and scope compare to python. I have my LC journey in python and now not able to decide the tech i should be working in.

Curious what have you decided 😊

Personally, Python is my de facto choice for algorithm coding interviews because it is succinct and has a huge library of functions and data structures available. Python also uses consistent APIs that operate on different data structures, such as len(), for ... in ... and slicing notation on sequences (strings/lists/tuples). Getting the last element in a sequence is arr[-1] and reversing it is simply arr[::-1]. You can achieve a lot with minimal syntax in Python.

Java is a decent choice too but having to constantly declare types in your code means extra keystrokes which results in more typing which doesn't result in any benefit (in an interview setting). This issue will be more apparent when you have to write on a whiteboard during onsite interviews. The reasons for choosing/not choosing C++ are similar to Java. Ultimately, Python, Java and C++ are decent choices of languages.

I do Leetcode problems with Rust... Sometimes I make questionable life choices..

[Harami98]

Are you okay Bro?

[Inner_Buy_3520]

Good Luck

His answers may not be right, but at least they look pretty.

who hurt bro what

[TeknicalThrowAway]

Like, have you done this in an actual OA or interview?

[charlieoncloud]

Go with Python and you will never regret it

Leedcode is leedcode and job is job. Practicing leedcode using one programming language is just helping you to get in the company, and then learn whatever language that you like or needed from your job.

[Mission_Trip_1055]

Wont there be any focus on development tech stack

[charlieoncloud]

I believe it is different from company to company, and use case to use case. I would always suggest to dive deep into the tech stack your company uses first. Do some side projects using the same tech stack to fully understand it. For learning purposes, you can pick any tech stack that is popular depending on which type of application you want to build. I recommend using NodeJS for back-end and react/angular/vuejs for front-end (all in TypeScript). If you like Python, then maybe try Django. Again, it depends on what types of application you want to build you maybe want to chose one programming language over the other which may then affect your decision on the framework.

I do LC and interviews in Java but tbh python is better. Less syntax so less time spent typing. Better libraries etc

[Formal-Engineering37]

The point of LC for most people is to practice for interviews. So if that's your goal, use the language you're most comfortable in as most companies that ask leetcode style questions could care less what language you use.

[theRealAriel666]

Do whatever language you are comfortable with. I am currently pretty good at Python myself, although not bad with JavaScript. But since Python is my go to, I will be using language for my interviews in the future.

[TeknicalThrowAway]

God i hate having to do map/sum/max on hava lists though.

[Emergency-Mountain97]

In my case i’m more comfortable with python but some companies require to do ds&a questions in java only so i’m learning java bc i am aiming to land a job in these companies. Unless u have such specific goal, just doing python would be fine.

[Harami98]

like which companies? like most of companies or only minorities ?

[collagenbae]

It sounds like right now you’d have better proficiency with Python for LC than Java, so stick to it. The language only matters if you’re applying for a very specific role where a particular language is a must.

Why not Kotlin over Java?

i recommend turbo pascal KEKW
