### Re: uva 12558

I have constraint on the upperbound of lcm of answer's denominator (1300*b),so I'm not sure if my code is real correct,here are some test data: 111 94 227 0 Case 1: 94/227=1/3+1/15+1/71+1/80585 94 227 1 3 Case 2: 94/227=1/4+1/9+1/19+1/4313+1/8172 94 227 2 3 4 Case 3: 94/227=1/5+1/6+1/30+1/71+1/80585...

### 12556 - "Center" of perimeter midpoints

the data set in the description "For example, if we can't use 2~6, the best solution is:2/3=1/7+1/8+1/9+1/12+1/14+1/18+1/24+1/28" is wrong,the correct answer is 2/3=1/7+1/9+1/10+1/12+1/14+1/15+1/18+1/28,I have checked this answer is correct... by the way,I don't think 15s for 100 test case...

### Re: uva live 5915 flight

Hope admin can add all offical tests,I got this problem accepted on codeforces gym, the test cases are stronger,but I don't think
6s for each test case is good,because O(n*m) brute force algorithm can run to test case 28....(32 cases in total) I want to test some other solution if it is strong enough

I think test cases for this problem is too weak,I write a weak solution,and got accepted ,but when I randomly test some official
test cases, my solution is wrong.... Hope admin can get test cases stronger

if it is not,it will be too hard to deal with. even it is hard to write a checker to judge if it is...
