You have defined j twice, once before testcases and once inside it.

Also see to it that the array might be of size 0 if q is 0 as there is no guarantee that m>n

Also I would suggest taking the inputs first and then trying your calculations because there might be some problem there

i have. also add cond if(q!=0) { ..... } and made changes in j then also it is showing runtime error. so pl check whats the problem now.and thank you for your interest. on running printf(cout) i found there is some error in "NO" one but not able to find it.

code #include using namespace std;

int main() { int t,j; cin>>t; for(j=0;j<t;j++) { int n,m,q,r,parth=1,khushi=1,k,l,sum1=0,sum2=0; cin>>n>>m; q=m/n; cout<<q<<" "; if(q!=0) { int p; p=qn; int arr[p]; sum2=(n(n+1))/2;

    
     for(k=0;k<p;k++)
     {
        arr[k]=0;
     }
     for(k=0;k<q;k++)
     {
        
        for(l=n*k;l<n*k+n;l++)
        {
            cin>>arr[l];
            sum1=sum1+arr[l];
            cout<<sum1<<" ";
        }
        cout<<endl;
        if(sum1!=sum2)
        {
            parth=0;
            break;
        }
       
        sum1=0;
     }
    }
           
    r=m%n;
    if(r!=0)
    {
     int arr2[r],hash[n+1];
     hash[0]=0;
     for(k=1;k<=n;k++)
     {
        hash[k]=0;
     }
     for(k=0;k<r;k++)
     {
        arr2[k]=0;
     }
     for(k=0;k<r;k++)
     {
        cin>>arr2[k];
        hash[arr2[k]]++;
        
     }
     for(k=0;k<r;k++)
     {
         if(hash[arr2[k]]>1)
         {
             khushi=0;

         }

Instruction to write good question
  1. 1. Write a title that summarizes the specific problem
  2. 2. Pretend you're talking to a busy colleague
  3. 3. Spelling, grammar and punctuation are important!

Bad: C# Math Confusion
Good: Why does using float instead of int give me different results when all of my inputs are integers?
Bad: [php] session doubt
Good: How can I redirect users to different pages based on session data in PHP?
Bad: android if else problems
Good: Why does str == "value" evaluate to false when str is set to "value"?

Refer to Stack Overflow guide on asking a good question.
