back to boardTo Admin: There must be something wrong in the testcase! In the description of input, "The second line contains K integers". If K = 0, the second should be empty line. But in Sample input #2 9 0 ??????.X? There is not so-called second line. So I read data like following. and got WA at 3. ---------------- Readln(N, M); if M > 0 then begin for i := 1 to M do Read(L[i]); Readln; end; for i := 1 to N do Read(T[i]); ---------------- Then I suppose sample input #2 is wrong, there must be an empty line in second line when K = 0. I change code like following. and got WA at 20. ---------------- Readln(N, M); for i := 1 to M do Read(L[i]); Readln; for i := 1 to N do Read(T[i]); ---------------- It implys there is some invalid char in input file. So I change code like following. and got AC. Readln(N, M); for i := 1 to M do Read(L[i]); for i := 1 to N do repeat Read(T[i]); until T[i] in ['X', '.', '?']; So there must be something wrong in testcase. Re: To Admin: There must be something wrong in the testcase! There was a bug in sample output #2. Tests are correct. |
