CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 6 months ago
Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 6 months ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: over 1 year ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: over 2 years ago
PlantUML, like Mermaid, is an open source tool that allows users to create diagrams from plain text descriptions. PlantUML is the original ‘diagrams as code’ platform. It has a deep feature set, can be integrated into just about any environment, and can be extended to fit just about any use case. For example, the most useful thing to me about PlantUML is its support for visualizing .JSON files. - Source: dev.to / about 19 hours ago
New version 3.0 of my PlantUML App for iPad is out with exciting update! 🤩 The new multi-modality feature now lets you transform hand-drawn diagrams into PlantUML scripts with just a pencil ✍🏻 or your fingers 👆. Take a look 👀 to this short on YouTube and download it from App Store to support me 👍🏻. - Source: dev.to / 2 months ago
Someone at work showed me https://plantuml.com/ recently. If you want your diagrams as code . Version controlled etc.. I highly recommend it. Source: 6 months ago
Open-source tool that uses simple textual descriptions to draw beautiful UML diagrams. - Source: dev.to / 11 months ago
Seems like a considerable upgrade from PlanUML (https://plantuml.com/ - which is amazing, but sometimes you just can't seem to be able to align the stuff the way you want too). - Source: Hacker News / 11 months ago
