in terms of lexicographic order, this combination is closer to the original data. It's not next in the book, it's before. d < h < u | | To admins: incorrect limitations. | Sergey Lazarev (MSU TB) | 1461. Christmas Garland | 31 May 2009 23:03 | 2 | There is no correct input for N=1. | | Strange printf behavior | it4.kp | 1461. Christmas Garland | 12 Aug 2008 04:17 | 11 | Strange but when i use
printf("%s",s.c_str());
I get WA on test 11, but if change it to
cout<<s;
it's become AC.
Can somebody tell me why? Well, I got WA 3 during the contest but I'm pretty sure my idea is right, ahy tests ? I first, have WA3 too.
That was because I misunderstood the problem statement...
I thought that there cannot be two consecutive segments with y=0 which is wrong. Please help me.
I still get WA on test 3
I'm a loser :(
Edited by author 31.07.2007 15:38 I don't know why you have WA, but even if you fix all your bugs you definetly get TLE, since next_permutation works in exponential time and the length of string could be 100000! Give me some tests please
I've WA #3
