801Binary Query Budget for Composite State 1A hidden system state is determined by a venue among 7 choices, a regime among 4 choices, and a throttle flag among 2 choices. Each yes/no query can return one bit. What is the minimum number of yes/no queries needed to guarantee identifying the full hidden state?脑筋急转弯简单brainteaser未尝试免费811Mixed-Outcome Signature Slack 1A diagnostic protocol has answer slots with outcome counts [2, 2, 3]. If it must encode exactly 11 hidden states, how many answer signatures remain unused under a perfect injective assignment?脑筋急转弯简单brainteaser未尝试免费815Mixed-Outcome Signature Slack 5A diagnostic protocol has answer slots with outcome counts [2, 2, 2, 3]. If it must encode exactly 19 hidden states, how many answer signatures remain unused under a perfect injective assignment?脑筋急转弯简单brainteaser未尝试免费816Modulo Checksum Recovery 1A packet contains integer fields modulo 7. The published checksum says the total field sum is congruent to 4 mod 7. You observe all but one field, whose visible values are [3, 5, 6, 1]. What is the missing field value modulo 7?脑筋急转弯中等brainteaser未尝试免费818Modulo Checksum Recovery 3A packet contains integer fields modulo 11. The published checksum says the total field sum is congruent to 4 mod 11. You observe all but one field, whose visible values are [8, 6, 1, 3, 5]. What is the missing field value modulo 11?脑筋急转弯中等brainteaser未尝试免费823Signature Feasibility Check 3A protocol has answer slots with outcome counts [3, 3]. Can it encode 8 hidden states injectively?脑筋急转弯中等brainteaser未尝试免费831Escort Cart Trip Count 12 staff members and 2 trained couriers start on one side of a corridor. A cart carries at most two people, and only couriers can drive it. Assuming at least two couriers are available, what is the minimum number of one-way cart trips needed to move everyone across if staff must always ride with a courier?脑筋急转弯中等brainteaser未尝试免费836Minimum Room Count 1Meetings occupy half-open time intervals [(9, 12), (10, 13), (11, 15), (14, 16)].
