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.

This is a week late, but through the FreeMediaHeckYeah sub, I was able to discover sejda.com , which is basically an (almost) all-in-one PDF editor website. Was neat to realize I didn't even have to download any software whatsoever. Source: over 3 years ago
Sejda.com - By far my most favorite experience but limits you to a # of docs per day. Source: almost 4 years ago
Might try sejda.com. Also as u/jakethepeg111 suggests, Libreoffice Draw could be an option. Source: almost 4 years ago
You need a Pdf file and then visit sejda.com. Source: almost 4 years ago
I use sejda.com for PDF editing. The best. Source: about 4 years ago
Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: over 2 years 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: over 2 years 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 3 years 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 4 years ago
