感觉cy弄这个PAT平台上的比赛，像天梯和这个CAIP，考验的主要是你的模拟能力和你的膀胱，之前天梯很多用模拟做，但是卡了很多py的小点
1
简单模拟题
N=int(input())for _ in range(N):M,D,C=map(int,input().split())if M>=8:print('Too late!')continueif M==7 and D>=12:print('Too late!')continueif M==7 or M==6 and D>20:if C==2000:print('Ok!')elif C<2000:print('Need more!')else:print('^_^')continueif C==1800:print('Ok!')elif C<1800:print('Need more!')else:print('^_^')

模拟题，主要就是对地图状态的更改以及新状态的判断
M,N,S=map(int,input().split())m2=2*M-1

题目我没仔细看，我先做的5结果后面想上厕所就没做，好像是暴搜找负环
好像输出 n-2 能薅个7分，这就是ioi

我用的BFS
