I'm also getting wa. Can u please tell me that should i handle negative number. Is there any negative number like
-1
or (-1)
Please give some I/O. Thankx in advance.

O(n) for each query is too slow.

Just set a note as a root, use dfs or bfs construct a rooted tree

and for each query, find the nearest common ...... of two node.

then odd or even ........

default:
if(expr[Pexpr] >= '0' && expr[Pexpr] <= '9')
{
int integer = 0; //**************** double
while(expr[Pexpr] >= '0' && expr[Pexpr] <= '9')
integer *= 10, integer += expr[Pexpr] - '0', Pexpr++;
data[Ndata++] = integer;
}


double also works, :D
my problem is that I use ...

sunmoonstar_love, the URL you provide has a problem alike. However, it is not helpful. What I need is a wonderful idea or the code.

Sorry, but I just want to tell Little Joey
where the problem can be judge :D

DFS is ok. :D

Don't have to construct a real N-dimensional array.

Why, I can't use double ??

I don't understand.

the problem can be found in

It is one from the 30th ACM/ICPC Hangzhou prem.....

Just use long double

double can't be used

I have dealed with the data above; but still wrong answer

any other trick?

my solution can pass other calculator problems efficiently.

but Wrong here.

Maybe negative integer exist in the input? or other tricks?

Thank you for your help! :D

#include<string.h>
double table[30]; // data as 'a'...'z'
char expression[10000]; // input string

thanks for your help,
