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.

Anita: I have lifetime access to the subscription-based code-learning website, CodeCombat, where I enjoy learning Python and taking all the Game Development courses offered there. Those games I made were a part of the Game Development 1 and 2 courses (there is also a 3rd course) on CodeCombat. You code the games entirely on your own from scratch by the use of the knowledge you have gathered from the lessons in the... - Source: dev.to / about 1 year ago
And https://codecombat.com, which has been around for a while now. I think this paradigm (navigating a character using "move" function invocations) is good but kind of exhausts its usefulness after a while. I question whether my daughter learns coding this way or just is playing a turn based top down platformer. The most code like thing is when you use 'loops' to have characters repeat sequences of moves. I... - Source: Hacker News / about 1 year ago
So now, while you have time (yes you have no time now but when you are out of school working with a child and or no summer vacation you will have less time) you can try MIT Scratch or CodeCombat and learn to code. For you it's a long the goal is to make 1 app or a handful of apps in 4 years until you graduate. That's absolutely doable even for someone who knows 0 about coding. Then when you graduate, if you are... Source: over 1 year ago
You can also have a look on Erase All Kittens (quite interesting) and also Code Combat. Source: over 1 year ago
Https://codecombat.com/ is REALLY good, the free levels have enough content for ~10 weeks for an intro to programming term. Source: almost 2 years ago
Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: over 1 year 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 1 year 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: about 2 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: about 3 years ago
