why i am getting SIGABRT error here?

Pay attention to compiler warnings!

@ssjgz may i know what compiler you use? these error diagnosis seems handy

All the information you need is there :slight_smile:

WHY MY CODE IS GETTING SIGABRT ERROR

Why am I getting SIGBART error in this code

Link:Solution: 56360155 | CodeChef

CODE:

using namespace std; 
typedef long long int ll;
int main() { 
    ios_base::sync_with_stdio(0); 
    int t;
    cin>>t;
    while(t--)
    {
     int m,x,pos;
     cin>>m>>x;
     vector<int>dp;
     cout<<"1 ";
     dp.push_back(0);
     dp.push_back(0);
     for(int j=2;j<=x;j++)
     { 
         vector<int> v;
     for(int i=0;i<j;i++)
     {
       v.push_back(i+1);
     } 
     pos=(m-1)%j;
     auto it=v.begin()+pos;
     v.erase(it);  
     cout<<v[dp[j-1]]<<" ";
     dp[j]=v[dp[j-1]]-1; 
     v.clear();
     }
     
     cout<<endl;
    }
    return 0; 
} ```

Here you need to look at the code. Without the code only by the name of this error, nothing can be said. It could be anything. Most often incorrect initialization or binding of elements.

#include

#include

using namespace std;

int main()

{

int T;

cin>>T;

while(T--){

    int N;

    string S;

    cin>>N>>S;

    int num = stoi(S);

    int XOR = 0;

    int temp;

    while(num){

        temp = num%10;

        XOR = XOR^temp;

        num/=10;

    }

   

    if(N%2){

        cout<<"YES"<<endl;

    }else{

        if(XOR==0){

            cout<<"YES"<<endl;

        }else{
