In my WA 42 programm output "No" In test#42 n = 1 then print Yes Thanks, but I think you are wrong.
I checked it:
int n;
...
int main()
{
cin >> n;
if(n == 1)
{
double *f = new double[0xfffffff];
cout << "Yes";
return 0;
}
...
}
And this code has WA (on test 42), but not Crash or Memory limit. Therefore n is no 1 in test 42.
I need some hints as before :-)
please :-) I add this code to my last solution and got AC...
if (n * (n - 1) == 0) {
cur = e;
ok = 1; // Yes
} It's strange, but I have WA 42 as before.
:-(
Who was need rejudge?
It's so strange. My desicion was AC (2 day ago), but now I don't know what can I do with this problem.
WA 42
I got wrong answer at test 33. does it enough to use
long long as data type. Use 0 or 1 to present matrix value's Thank u very much Anton , I got accepted. I don't know why i didn't think about that Still i am quite a stupid.

Edited by author 03.11.2006 09:37 Hello collegues ! :)
Can you tell me ... are you geting matrix B (with 0 1).
I tried that way and got TLE.
it comes about n*(n+1)*n^3 operatons.
Maybe there are more soft methods...
Try use express method (for example A^5 = (A^2)^2*A Thank you my Friend!
AC.
Ti daril mne RADOST' (I eto v jizni glavnoe)...:) But erection of a matrix in a square borrows n^3. => O(2n*(n^2)*n^3) and this had TL(((
Maybe erection of a matrix in a square can work more quickly?
Edited by author 16.09.2007 14:32 I add this code to my last solution and got AC...
if (n * (n - 1) == 0) {
cur = e;
ok = 1; // Yes
} It's strange becanse N>=2 according to problem statement |
