Let's hope this is going to help me solve some more Project Euler [1] problems! [1] https://projecteuler.net/. - Source: Hacker News / about 2 months ago
Https://projecteuler.net/ for "Thinker" brain food. (it still has the issue of not being a pragmatic use of time, but there are plenty interesting enough questions which it at least helps). - Source: Hacker News / 5 months ago
I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 7 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago

Leetcode.com for problem solving practice. Do basics first before jumping into this one. Similar thing you can do at topcoder.com for trying to code with a timer. Great for problem solving practice. Source: about 3 years ago
I know topcoder.com does competitive programming for $$, I haven't done it myself though so I'm not entirely sure how it works. Source: over 3 years ago
One thing I noticed is topcoder.com is in "Advanced" and I'm not sure but, how is Top Coder any more advanced than others? Source: about 4 years ago
Usually, I go to hackerrank.com or topcoder.com to choose the easiest challenge and I do it. In that way, you can compare your solution with other ones and get better. Source: over 4 years ago
