UWA week 37 (2nd semester, week 7) ↓

Lab 04 - Question 05 (all 8)

2:02pm Wed 11th Sep, Adam W.

Yes it does appear to be an issue with the parenthesis, I tried adding them into the correct solution on the test interface and it does appear to break it, I'll investigate if this is an SQLite issue, or to do with the testing code implemented on the question itself. So for now don't use parenthesis for this one. Adam. "Yufang Wei" <24*1*1*3@s*u*e*t*u*a*e*u*a*> wrote:
