@marcelljason06: This doesn't repair it - yet at least the function seems to be returning some undefined values sometime (i.e. it sometimes reaches the end of function - and there is no return or something) Also char* is not scaned with "&" but guess thats just detail :) But I don't know how it shall work - so .. no clue how to behave futher :/ |

@singhaljoy: Firstly - you have "WA" on test-case "1", not "12" .. secondly don't think the problem is in a "corner" test-case but handling multiple test-cases Good Luck & Have Nice Day |

@hanstan: Hello, the maximum is 100, anyway this information might be slightly "misleading", because the number of test-cases depends on sizes of maps. ^_^ |
