When I ran ./scripts/test_algo_linux python-algo/, it tells me that ./scripts/test_algo_linux: /lib64/libc.so.6: version GLIBC_2.18’ not found (required by ./scripts/test_algo_linux)`. How can I solve this?
Sounds like you are running an older version of Linux/Ubuntu than the version that compiled test_algo_linux. Hopefully, C1Ryan might get around sometime to compiling it again from an older version of Linux/older libc, but I’ve always personally had trouble working around this kind of problem, besides by just upgrading your distribution!
Yeah, I also wanted to upgrade, but sadly without root permission 
Software engineering with a borrowed computer/one you can’t fully control is generally very hard! You might just have to rely more on the website for testing then
