The case in witch memory limit is exceeded is case 4, so the map will have 1 entry nxj->vector of all above numbers, which is not much by any means. Is there something I'm missing?

Sometimes I can't see the test cases (mine or anyone else) on the status page, did something change or there is a problem?

Edit: It is a bug and will be fixed — > http://codeforces.net/blog/entry/54061#comment-381339
