### Re: 11366 - Circle of Debt

If the judge data is the same as the original contest data, I think it is wrong: The forth case is: 1 5 0 1 0 0 0 0 0 0 1 1 1 2 10 0 0 5 0 0 5 This means that before the exchange Alice has 100, Bob has 100 and Cynthia has 25 crowns. Since Alice has to pay Bob 1 crown, and Bob has to pay Cynthia 5 c...

i think each set of input of first line may contain a float number, not an integer number, i.e. the degree of polynomial may give like 3.0 .

i use

i use

**scanf("%d")**and get TLE, but use**scanf("%s", word)**and**n = atoi(word)**get AC.- Fri Jan 25, 2008 3:27 pm

### it is an unavailable input = =||

getting wrong answer a lot of times and finally ACCEPTED!!! i think it is a normal bfs problem but the starting time doesn't have a range, namely the starting time can be very large, more than 24, so after you read the starting time, you need to mod 24 , and then judge wheter it is <=6 or >=18. if s...

i still don't know why.rio wrote:Send a code with commenting out below part.You could guess why its getting TLE.Code: Select all

`if(t>dp[i]) dp[i]=t; if(dp[j]>dp[i]) dp[i]=dp[j];`

does it mean that it costs a lot of time to do float number comparison?

### 11285 - Exchange Rates

i use O(n^2) solution but seems it does not expected, i got TLE.

it's very strange because the limit of n is 365, so i just want to check do i really have to implement an O(n) solution?

Finally, I get AC :D I use a lot of OLE and get some conclution: (In one case...) - A line may not contain exactly 2*N numbers, maybe less than it, maybe more than it. Moreover, it is possible that there are no numbers in this line!! So if you use C or C++, you'd better use gets(). - Although you do...
