“I knew this problem.”
“Classic Dijkstra setup.”
“I fumbled the opener because I started listing tariff numbers instead of structuring the problem.”
“Went through my usual stack but fumbled a bit trying to connect each tool to a concrete project on the spot.”
“This was the meat of both rounds.”
“This question is four questions stitched together and they absolutely expect you to hit all four parts.”
“I got the brute force out pretty quickly, O(n^2), try removing each element and recheck for a pivot.”
“Looks easy and it mostly is, but the modular wrap on the verification string index is the thing that trips people up.”
