The question some queries which required finding the diameter of a the graph, had indescriptive explanation for the diameter of the graph. It described the diameter to be the maximum distance bw 2 graph nodes while in actuality, diameter refers to the maximum minimum distance between 2 nodes. This discrepancy caused utter runtime errors and submission mistakes. Since, the question demanded the maximum distance rather than maximum minimum distance, I wrote my code accordingly to the question. This hampered with my contest experience and prevented me from gaining a substantial increase in my elo for my division because it was the highest rated question for my division. It would be very kind if you could look into the matter, rectify the issue with the problem description and provide me with the rating I would have for that question submission. You awarding this elo would greatly help me.
