“Took longer than it should have.”
“The base implementation wasn't too bad once I landed on a min-heap ordered by run time.”
“This felt like a Pinterest-flavored question from the start, which I thought would help me but it kind of made me overthink it.”
“This one made me pause longer than I expected.”
“This one is nastier than it looks.”
