So in order to get better at leetcode is a good path of progression: Start with data structures (any and all) -> move to algorithm easy -> move to algorithm medium? I was a shitty coder. Everyone talks about Leetcode as if it’s a piece of cake. That’s a total waste of time in my opinion. Cookies help us deliver our Services. Many LeetCode questions were either similar or exactly the same as the ones asked in interviews. If you count the total number of software engineers in the job market (including new grads, professionals, self-taught devs, and Bootcamp grads) and compare that to the number of job openings, you’ll end up with the following figure: Companies are desperate for SEs — if you can only prove that you’re good enough, they’ll take you. Don't get psyched out. Before you do anything, make sure to review/learn the topics below. The competition for getting a CS job is at its peak, therefore expect only hard questions to show up in a interview. Yea when I started hackerrank I could barely do the easy problems . It's not too math heavy, and the second half of the book are war stories of using the algorithms which really helps solidify their usage. Print binary tree using DFS (in-order, preorder and post order — all three of them) and BFS. On one hand, I want you to take all of this seriously. Win programming... 2. Especially if it's a problem where I needed to look up the solution! You gotta just sit and practice. Know your motivations. Press J to jump to the feed. I definitely did this for the fundamental questions, stuff like reverse a linked list and two sum I did once every couple of weeks until I knew it like the back of my hand. Grind leetcode all day until you can do hards without thinking. And sometimes I forgot how I did it and had to spend another 40 mins or an hour to attend. Start with the absolute easiest ones to build up confidence. The book is good, but it does include mathematics in certain sections (which OP shouldn't shy away from). Then reimplement those good solutions. get into a big-n, unicorn, or fintech company with 100k base salary directly out of school. I find that funny because many recent grads also feel discouraged by thinking that they’ll be up against “professionals” with “real life experience” (whatever that means). Use These Two kubectl Commands Instead! Another source I recommend is www.geeksforgeeks.org. Would you say CTCI is adequate prep for leetcode? Remember the two following rules: 1. I always do! You see this in the intro pages (this is easy math if you know discrete). As mentioned by others, use hackerrank instead or Codefight. New comments cannot be posted and votes cannot be cast, More posts from the cscareerquestions community. It's okay to look at some of the solutions, this is so you can get a feel for these types of algorithms. Those you who have done 50-200 leetcode questions, do you ever go back to problems you already submitted accepted solutions to? Conversely, you’ll be lost if you spend too little time on the prep work. Absolutely. I'm pretty sure even BigN companies aren't asking only Leetcode Hards. --or maybe not...I can't figure out what this is..

My learnings: Start small and work up. Imo not worth the time investment unless you didn't get optimals first time round. Some people study way more than they need to (ex fancy graph algorithms, Spanning tree, A*, etc) because they think that’ll make them better engineers. Why do you want to "get good at Leetcode"? Learning anything additional may be a total waste of your time. These are the most difficult moments of your engineering career life. I guess I just wonder my lack of skill is in the algorithms. I want to sincerely wish you luck in this journey. I answered over 160 problems over the course of a few months. Keep a notebook if you like. On your main Leetcode profile page: Rating seems to be your skill at solving problems?. If OP doesn't know discrete math, they may be lost in those sections. In reality, there is basically no competition. it may take up to 6 months. 3. If you practice smart and solve enough problems on Leetcode/CTCI, you’ll be in good shape. Nothing more, nothing less. In my experience, it's the best book to get started in advanced algorithms and data structures. So even the easy algorithms are hard for me. More often than not the solutions I see involve a really nice solution in like 5 lines that really exploit x data structure. 2. I … Once you’re done with that, you may move on to the next step.
