"persistence is key" and a site to for persisting at leetcode.

this kills the joke, however.

I thought they asked about the dang_fan username.

The user seems to be struggling at leetcode, so he needs some persistence to get there until he is able to do it.

“stop forgetting LeetCode patterns”

“persistence” (in the data sense, rather than the personality trait sense) “is key”

it’s a double meaning, no? as the thing with leetcode is that the way to best it is persistently doing it.
