Thanks for your great help!

Your tricky test case really useful. This test case fail my algorithm. It's seem that I should refigure out a better algorithm to prevent this kind of test case..
By the way, Thanks for paying so much attention to my problem ^^.

According to your input data, my program can produce the right answer. And I also add some code to ignore the number that > 50 but still got Wrong Answer! :cry:. I haven't started to optimize my efficiency of my program but at least there is some simple input case that I still don't consider in my p...

Can anybody help me what the flaw of algorithm I used in this problem? :cry: 1.read in all sticks, store them in a array and sort them in a decreasing order according to their length. 2.when reading in the sticks, I also use a variable to record the maximum length stick and sum of all sticks length....

I have test as many case(negative number,empty tree) as I can, but still get WA, can anybody help me? /* problem 112 C++ */ #include<iostream.h> #include<vector> char cursor,sign,precursor; int num,query,i,j,sum,level; bool result; using namespace std; void main(void) { vector<int> numlv; vector<int...

Here is my code:) #include<iostream.h> #include<stdlib.h> struct bumperprofile { int value; int cost; }; short row,col,bumpernum,bumperrow,bumpercol,i,j,index; short ballrow,ballcol,lifetime,direction,oricol,orirow; int wallcost,totalscore,partialscore; void main(void) { while(cin>>col>>row) { short...

Does this problem have any special test case to let me get WA?

#include<iostream.h> #include<math.h> #include<vector> using namespace std; short N,C,i,j,count,midindex,temp; void main(void) { vector <short> primelist; primelist.push_back(1); primelist.push_back(2); primelist.push_back(3); for (i=4;i<1001;i++) /* make a list of prime number at range 1 to 200 (i...

Does anybody know any other ACM forum ??

Any tricky input in this problem?? I got WA so many times...

Does anybody have any idea of tricky input ?? I got so many times wrong answer...><

Here is my algorithm: 0.three array: ignore,title,keyword(also store "the title it come from"and "keyword position in the title"). 1.Read in words to ignore and stored them in a array(ignore). 2.Read in titles, one word at a time to a string.(If read in a upper case letter, it wi...

Can anybody help me why I always got Runtime Error (signal 11 (SIGSEGV) Invalid memory reference )? :cry: #include<iostream.h> #include<string.h> typedef struct /* structure for transaction */ { char accountnum[3]; /* transaction account */ float money; /* transaction charge */ }transac; typedef str...

dawynn is right !! Got accepted is just a little meaning..What you learn from coding is the most important.

Your wisdom really do me a great favor. I finally got accept!! Thank you for paying so much attention to my problem
