591 - Box of Bricks

[angga888]

Hmm.. weird... It should be correct

Maybe you can check the error message from the email sent by the judge.

[kckckc]

Thanks

I submit the same code for a few times and finally it "Accepted"

I don't know where the problem is but now is correct

[J&Jewel]

This is a very interesting problem....
Suddenly may be the judge server some times show false...
I also solve a problem....yesterday it shows w/A.....today it shows ACC...
Very Interesting....

Can anyone please tell me what's wrong with this code:

#include <stdio.h>


main()
{
int n,h[200],sum=0,sum2=0,h1[100000];
int k=0,i,j;

while(scanf("%d",&n) && n!=0)
{
for(i=0;i<n;i++)
{
scanf("%d",&h);
sum+=h;
}

sum=sum/n;

for(i=0;i<n;i++)
{
if(h-sum>0)
{
sum2+=(h-sum);
}
}
h1[k]=sum2;
k++;
sum=sum2=0;
}

for(j=0;j<k;j++)
{
printf("set #%d\n",j+1);
printf("The minimum number of moves is %d\n\n",h1[j]);
}


return 0;
}

thanks

your mistake is:you take all the inputs together and then print their outputs, but actually this is not the usual style for uva problems.
here you'll have to take an input, then print its output,then take another input........this process will go on until the end of the file.
you can have a look on the sample code provided in this site.

I really can't find any mistakes...Pls help me~~~


#include <iostream>
using namespace std;
int main(){
int count=0;
int block;
long sum;
long result;
long diff;
int i;

do{
sum=0;
result=0;
cin>>block;
if (block==0){
break;}
count++;
int a[block];
for (i=0;i<block;i++){
cin>>a;
sum+=a;
}

for (i=0;i<block;i++){
diff=a-sum/block;
if (diff>0){
result+=diff;}
}
cout<<"Set #"<<count<<endl;
cout<<"The minimum number of moves is "<<result<<endl<<endl;

} while (1);

return 0;
}

This is my code cant find why i get P.E
plz help me

#include<iostream>
using namespace std;
int main()
{
int i=1,k,h[100];

cin>>k;
while(k!=0)
{
int sum=0;
for(int j=0;j<k;j++)
{
cin>>h[j];
sum=sum+h[j];
}
int t=sum/k;
int s=0;
for(int j=0;j<k;j++)
{
if(h[j]>t)
s=s+(h[j]-t);
}
cout<<"Set #"<<i<<endl;
cout<<"The minimum number of moves is "<<s<<"."<<endl;
cin>>k;
i++;
}
return 0;
}

thanx in advance

Hey...

Try changing line

Code: Select all

cout<<"The minimum number of moves is "<<result<<endl<<endl;

with line

Code: Select all

cout<<"The minimum number of moves is "<<result<<"."<<endl<<endl;

Then, you'll get ACC

[augustotorres]

Try changing line

Code: Select all

cout<<"The minimum number of moves is "<<s<<"."<<endl;

with line

Code: Select all

cout<<"The minimum number of moves is "<<s<<"."<<endl<<endl;

Good luck

[Debashis Maitra]

Please remove your code after AC

[dorpon]

can any one plz tell me what is the prob in my following program
#include<stdio.h>
main()
{
int x[100],n,i,y,z,l,k,j=1;
while(1)
{
y=0; l=0;
scanf("%d",&n);
if(n==0)
break;
for(i=0;i<n;i++)
{
scanf("%d",&x);
y+=x;
}
z=y/n;
printf("set# %d\n",j);
for(i=0;i<n;i++)
{
if(x>z)
l+=(x-z);
}
printf("The minimum number of moves is: %d\n",l);
j++;
}
}

[vijay03]

Two things:

Code: Select all

 printf("set# %d\n",j); 

should be

Code: Select all

 printf("Set #%d\n",j); 

And you forgot this line:

Output a blank line after each set.

HI, Having eventually managed to get an AC I know get a PE. I know it's not a major issue but I'd like to clear up what I might have got wrong. I copy below the i/o parts of the cod ein the hope that someone will guide me.

With thanks

Code: Select all

cin >> stackTotal;
// outer loop only entered if the stack total is not zero
...
cin >> stacks[i];
...
// process the stuff and do some calculations
// print out the result
cout << endl << "Set #" << count << endl;
cout << "The minimum number of moves is " << answer << "." << endl << endl;

[abdullah<cse du>]

Hi,

There is a wrong in your output section. Your output section is

Code: Select all

cin >> stackTotal; 
// outer loop only entered if the stack total is not zero 
... 
cin >> stacks[i]; 
... 
// process the stuff and do some calculations 
// print out the result 
cout << endl << "Set #" << count << endl; 
cout << "The minimum number of moves is " << answer << "." << endl << endl; 

Change it to

Code: Select all

cout <<"Set #" << count << endl; 

I think it will help you.
ABDULLAH.

can someone please give me some help in speeding up my program as i'm getting tle...

Code: Select all

#include <iostream>

int main()
{
	int n,h=0,average=0,moves=0,set=1;
	int* heights = new int [60];
a:	
	scanf("%d",&n);
	if(n<1)
	{
		return 0;
	}
	else
	{
		while(h<n)
		{
			scanf("%d",&heights[h]);
			average+=heights[h];
			h++;
		}
		h=0;
		average=average/n;
		while(h<n)
		{
			if(heights[h]>average)
			{
				moves+=heights[h]-average;
			}
			h++;
		}
		printf("Set #%d\nThe minimum number of moves is %d.\n\n",set,moves);
			moves=0;set++;
			goto a;
	}
}

thanks
