where to practice competitive programming in common-lisp?

As far as I know, only code-chef and spoj support common-lisp. And both of them return NZEC, when I submit solutions in common-lisp. Any suggestions?

Hi.

• By far the best quality site for competitive programming at which you can use Common Lisp is AtCoder. It provides most problems from rated contests in English. A drawback is, however, that no English editorial is provided for beginner contests. Other famous and international sites include CodeChef, CS Academy, HackerRank, HackerEarth, and Kattis.
• You can see other people's submissions in most sites. (Exceptions include Kattis.)
• Most sites provide an online test environment: e.g. here at CodeChef.
