Your f function isn't working properly. If 1 is inputted the output should be 1 however in your case the output is 0.

Sorry my bad

Old Code:

I printed a blank line between test cases as brianfry713 said but that wasn't enough to get AC. After implenting lighted's modification it worked but I don't understand how that change works since I seem to be getting the same output for all of my test cases.

Ok thanks. I've adjusted my code. Now I get runtime error

Hello
I've tried several test cases on mine. I'm not sure why I'm getting WA


I got AC Thanks :)


I've noticed reading through this thread that the input output is of the format

#testcases

#computers
cmd1
cmd2
cmd3
...

#computers
cmd1
cmd2
...



My code isn't made to handle this but I read ...

You're code checks if the differences sum to what they would sum to if each difference in the sequence was accounted for. However there are cases when the differences sum correctly but not all differences are accounted for.

Try this

1 1 4 7

This sequence isn't jolly but I believe your code will ...

Correct.

When I was trying to figure out the problem I came across this article, and that is one of the things which messed up his algorithm

Thank you very much. I got it accepted now.

I'm having an issue with my code. It works for the sample input but I get RE when submitting

#include <stdio.h>
#include <map>
#include <vector>

using namespace std;

typedef vector<int> vi;

class UnionFind{
private:
vi p,rank;
int singles, sets;
public:
UnionFind(int N){
singles=sets=N ...

I adapted it to use gets(), I've got Accepted now. Thank you very much for the help

I've modified my code. I haven't figured out how to address all the issues you mentioned but here it is

#include <stdio.h>
#include <map>
#include <string>

using namespace std;

int main(){
int TC,tot;
double p;
string name;
char* str;
map<string,int> m;
scanf("%d",&TC);
while(TC--){
tot ...

I'd like to solve it using STL map but I'm having some issues.

#include <stdio.h>
#include <map>
#include <string>

using namespace std;

int main(){
int TC,tot;
double p;
string name;
map<string,int> m;
scanf("%d\n\n",&TC);
while(TC--){
tot=0;
while(scanf("%30s",name.c_str())==1){
m ...

I'm having trouble with the IO in this problem. I enter the first line of numbers then I go to the next line and the program ends. It might be because I'm doing it in cmd. I've tried using "type UVa10038.in | UVa10038.exe" to input all data but I get similar results. My program doesn't print ...

Ahh I see. I did learn to return 0, but I'm still new to C++ so I guess it hasn't completely sunk in yet. Thanks for the help, I really appreciate it.

I've tried all the test cases given in this thread and I get the right answer for all of them. When I submit my code I get a runtime erorr. I've checked it for array index out of bounds and division by zero and I'm pretty sure those errors can't happen.

#include <stdio.h>

int main(){
int ...
