Webdp[v] — is bitset of reachable vertexes (vertexes of our supplementary graph). And so complexity is M 2 / 32 for both memory and time. However memory complexity can be boosted (thanks to ch_egor): You can go with scanline over edges, answering queries in … WebCodeforces. Programming competitions and contests, programming community. F# feels as high-level as Python but it is faster than Pypy thanks to static typing (even faster than Java due to the native support for Value Types). It provides additional data structures like BitArray/Bitset and BST in the standard library.
Web1 The package for this problem was not updated by the problem writer or Codeforces administration after we've upgraded the judging servers. To adjust the time limit constraint, a solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then the value 800 ms will be displayed and used to ... WebAs for performance it takes 8 time less memory. It may help in some tasks. Similar result can be achieved with bitset. The major differences being that bitset is fixed size but …
