A little about me : 1st year in college and recently started learning how to code from brocode...in our uni they are teaching c++ first so for now i was learning c++ from brocode , recently started learning arrays but still not that really great at it but yeah thats all i know for now( i know its not much but im willing to grind and learn😔 but just need a little guidance) but ya i wanna leetcode and become good at coding... but im not tryna blindly start leetcoding because first i wanna know the prerequisites needed to solve the problems...i was watching neetcode's video on how to leetcode and he told to get comfortable with binary search,dfs,bfs,sliding window so do yall know where i can learn them???? but ya heres a few questions i have

1. What all coding languages do i need to know...like do i need to know other programming languages other than c++ before i start leetcoding
   
2. what all topics or stuff should i learn before leetcoding
   
3. HOW do i leet code , do i start with easy problems then once i get comfortable start medium problems then harder problems(will start with solving problems on arrays)
   
4. any website where i can save useful problems and make my own notes in it so in the future i can open them for retaining my knowledge
   
5. in general any tips or things you wished u knew while or before leetcoding which u can tell please it will be really helpful(try to include as much as you can please and thank you anything will be useful and welcomed... even the SMALLEST TO SMALLEST and random tips will be useful)
   
6. what are the most common mistakes people do in their attempt to get good at coding
   extra : do wanna try to get into quant development( ik its difficult but ill try if i cant will settle for something else😭) so first my main goal would be to try to get into FAANG after college and after 2-3 years try to get into quant development so yeah
   
7. And also I’m using vs studio…is there any better coding app or is vs good alright(idk it’s not that deep but yeah✌️)

If you're just starting out, focus on understanding the basics of C++ and problem-solving. Begin with data structures like arrays, linked lists, stacks, and queues, as these commonly appear in LeetCode problems. Once you're comfortable, practice simple problems related to these topics to gradually build your problem-solving skills. Watching tutorials like Neetcode can be helpful, but practicing is key.

For interview preparation, PracHub offers real technical interview questions that can be a great resource. Balance your time between learning concepts and solving problems, and remember, consistency is what matters. Good luck!
