### 10700 - Camel trading

Sorry for putting this topic in volume CVI but at thismoment ther is not Volume CVII.

I don't know why i'm geting WA.My solution is good solution I use DP and get right answers for simple input.

I saw that nobody at this moment have got this problem AC by Pascal.

Whats wrong.

Well, I just got accepted in Pascal (with my alter ego account xenon, else it wouldn't show up in the list ), so there shouln't be any problem.

You can use DP, but, as Per stated somewhere, there also is a greedy approach which is a lot faster. And like him, I'm also not 100% convinced that it works for all special cases. But hey, AC is AC.

Hello little joey If you got AC by Pascal then tell me please did you use Longint or something else int64,qword..?

### Pascal.

Greetings all!

I solved this one in Pascal too.

I used QWord.

I made it in a pretty mechanical way

A couple of arrays of strings, and such.

Got time 0:00.598, but ACed

Keep posting!

Did you define infinity correctly? That was my problem.Eduard wrote:I don't know why i'm geting WA.My solution is good solution I use DP and get right answers for simple input.

AC

EDIT:

To anyone else who may have the same stupid problem I did. The string I used to hold the expression was a char array of size 24 (at most 12 numbers, at most 11 operators, plus the '\0'). However, I forgot that some numbers could be 2 digits, which means the array size should have been at least 36

Examiner was right i made the infinity wrong because i write it for longint and infinity=maxlongint.Now I chang infinity=5*10^15 and got AC.
