...For a "set", S[i] represents the difference in money (prefixes and oh ~) from day I to fa[i] days. For each piece of information, if L and R are in the same set, the prefix and the differential are directly used and compared to Val, if not in the same set, merge two sets. Draw your own hand to see what the situation is.1 /**************************************************************2 problem:12023 User:programmingape4 language:c++5 result:accepted6 time:112 Ms7 memory:808 KB8 **************

The prefix and the relationship are processed first, and then it is obvious that this is a differential constraint. So that's the shortest-circuit problem.By the way to review the SPFA plus SLF optimization is how to write, also learned to another stl--deque two-way queue.#include 　　BZOJ-1202 cunning businessman.
