What was the longest you ever spent trying to fix broken code

ok so I was working on android rat (remote access tool) and I was trying to figure out after saving the users in a hasmap based on imei using listview, I slept on it and realized I can make a second list that will replicate that will only store the IMEI, while the UI list will have user info.. so when I received the index number (lets say 4th users) it would use the index of 4 on the second list (which stored the imei) and retrieve info and diagnostic options.

oh this took 3 days to solve, also I didn't sleep on it, that was another problem. I figured it out when I was in my medieval history class in college.

When I started learning programming in PHP I could sometimes spend quite a bit of time on syntax errors. Now I almost never write syntax errors to begin with and when I do I am able to fix them usually within 10 seconds with help from the error message in just about any C-style language.
