Any trick in getting AC instead of PE on this problem 441 (Lotto)? I tried couple newline variations but still no luck.

Between every output set you should put a new line.
Remember

The test cases have to be separated from each other by exactly one blank line. Do not put a blank line after the last test case.

Also exactly one space between integers sholud be followed.

See the sample ouput for input

Code: Select all

7 1 2 3 4 5 6 7
7 1 2 3 4 5 6 7
0

Output

Code: Select all

1 2 3 4 5 6\n
1 2 3 4 5 7\n
1 2 3 4 6 7\n
1 2 3 5 6 7\n
1 2 4 5 6 7\n
1 3 4 5 6 7\n
2 3 4 5 6 7\n\n
1 2 3 4 5 6\n
1 2 3 4 5 7\n
1 2 3 4 6 7\n
1 2 3 5 6 7\n
1 2 4 5 6 7\n
1 3 4 5 6 7\n
2 3 4 5 6 7\n

If same you owe an AC.

Hi,
Sorry for reviving an old thread,but I am not sure why am i getting WA:

Code: Select all

#include<stdio.h>

int main()
{
int i,j,size,a[49],b[6],l,k,m,n;


while(1)
    {
    scanf("%d",&size);
    if(size==0)
        break;
    for(i=0;i<size;i++)
     {
	 scanf("%d",&a[i]);
	 if(i<6)
	   b[i]=a[i];
	 }
    
    j=4;
    l=5;
    n=l+1;
    m=size;
    
    for(i=0;i<6;i++)
       printf("%d ",b[i]);
   
    while(j>=(-1))
	{
    if(l>j)
	{
	if(n<m)
	   {
	   b[l]=a[n];
       printf("\n");
       for(i=0;i<6;i++)
	      printf("%d ",b[i]);
       n++;
	   }
       else
	    {
        n=l+1;
	    l--;
	    m--;
    	}
	}
    else
	      {
	      k=0;
          for(i=0;i<7;i++)
		     {
		     if(i==j)
			   continue;
		     b[k]=a[i];
		     k++;
		    }
		  n=i;
	      if(j>=0)
          {
          printf("\n");
		  for(i=0;i<6;i++)
		      printf("%d ",b[i]);
	      }
          j--;
	      m=size;
	      l=5;
	   }
      }
printf("\n");
}
return 0;
}

Two things i can say:

1.you code does not follow this-

The test cases have to be separated from each other by exactly one blank line. Do not put a blank line after the last test case.

2. This print a space after the last number,which should no be.

Code: Select all

  printf("%d ",b[i]);

I have modified the code as what u have said,still no luck:

Code: Select all

#include<stdio.h>

int main()
{
int i,j,size,a[49],b[6],l,k,m,n,c=0;

while(1)
    {
    if(c==1)
     printf("\n");
    scanf("%d",&size);
    if(size==0)
	break;
    for(i=0;i<size;i++)
	 {
	 scanf("%d",&a[i]);
	 if(i<6)
	   b[i]=a[i];
     }
    c=1;
    j=4;
    l=5;
    n=l+1;
    m=size;

    for(i=0;i<6;i++)
       {
       printf("%d",b[i]);
       if(i<5)
           printf(" ");          
       else 
           printf("\n");   
       }
    
    while(j>=(-1))
	{
	if(l>j)
	  {
	  if(n<m)
	    {
	    b[l]=a[n];
	    
	    for(i=0;i<6;i++)
	      {
          printf("%d",b[i]);
          if(i<5)
           printf(" ");          
          else
          printf("\n");  
          }

	    n++;
	    }
	  else
	    {
	    n=l+1;
	    l--;
	    m--;
	    }
	   }
       else
	   {
	   k=0;

              printf("%d",b[i]);
              if(i<5)
                 printf(" ");          
              else
                 printf("\n");
              }
        }
		j--;

	    }
	 }
     
   }
return 0;
}

I tried 10 more test data and it was all right. But Bad OJ(Sorry

) says it's WA
I don't no why it is

Please help me.....
Please give some critical inputs......
Or hint from code.

Sorry, But I'm using C++.

Code: Select all

#include <iostream>
using namespace std;
int s[13];
int Base2[13];
int main()
{
	int	k;
	int i, j;
	int ktimes2;
	int cnt = 0;
	int imsi;
	int cntzero = 0;
	int first = false;
	while (cin >> k){
		if (k == 0) break;
		if (first) cout << endl;
		first = true;
		for (i = 0; i < k; i++){
			cin >> s[i];
		}
		
		ktimes2 = 1;
		for (i = 0; i < k; i++){
			ktimes2 *= 2;
		}
		for (i = 0; i < ktimes2; i++){
			imsi = i;
			for (j = 0; j < 13; j++){
				Base2[j] = 0;
			}
			cnt = 0;
			while (imsi > 0){
				Base2[cnt++] = imsi%2;
				imsi /= 2;
			}
			cntzero = 0;
			for (j = 0; j < k; j++){
				if (Base2[j] == 1) cntzero++;
			}
			if (cntzero == 6){
				for (j = 0; j < k; j++){
					if (Base2[j] == 1){
						if (j != k-1){
							cout << s[j] << " ";
						}
						else cout << s[j];
					}
				}
				cout << endl;
			}
		}
	}
	return 0;
}

it's a very easy problem if your approach is iterative backtracking.
since you need to take a fixed(6) numbers at a time, you can iterate 6 loops. and the limit of k is 6<k<13, so no possibility of getting tle!!

Posted: **Fri Aug 02, 2013 2:54 pm**

I have tried this problem more times than I can count. But every time I get the damn "Submission Error".

I don't know why OJ showing this. Has anyone got any idea?

I am using C++ stl funtion "next_permutation" and a vector to store data.

Instead of using recursion, you can solve this problem using 6 nested loops

For me, it ran in 0.015 seconds.

Hello , I'm relatively new in that and i tried solve this problem i used linux diff comand to compare my output with required output and is the same but when I submitted was WA someone can look to my code please.

Code: Select all



#include <bits/stdc++.h>


using namespace std;

typedef vector<int> vi;
typedef pair<int,int> ii;
typedef vector<ii> vii;
typedef pair<string,string> ss;
typedef vector<ss> vss;


#define all(a)                      a.begin(), a.end()
#define in(a,b)                     ( (b).find(a) != (b).end())
#define pb                          push_back

int main(int argc, char const *argv[]) {
  int n;
  vi v;

  cin>>n;
  while(n!=0){
    while(cin.peek()!='\n'){
      v.pb(n);

      cin>>n;
    }
    v.pb(n);
    sort(all(v));
    auto it = unique(all(v));
    v.resize(distance(v.begin(),it));


    for (int i = 0; i < v.size(); i++) {
      for (int j = i+1; j < v.size() && v[i]!=v[j]; j++) {

                cout<<v[i]<<" "<<v[j]<<" "<<v[k]<<" "<<v[l]<<" "<<v[z]<<" "<<v[x]<<endl;
              }
            }
          }
        }
      }

    cin>>n;

    cout<<endl;

Try taking the input in a simpler way as below..

Code: Select all

while (cin >> n) {
   if (n == 0) break;
   
   v.clear();
   
   // Read set
   // No need to sort as the input is already sorted.
   // We also assume that there is no duplicate in the set
   
   if (testcase > 1)
      printf("\n");
      
   //  Process and output here..
}
