Why do I get a SIGABRT error here?
For now, you should probably be more concerned about why it’s giving the wrong answer for the Example Input (there’s little point in submitting a solution until - at minimum - it gives the correct answer for all provided examples).
Who knows? While debugging that, you may or may not find your answer

Not sure if this is a valid testcase (seems to meet the Constraints, at least), but consider the test input:

//why i am getting SIGABRT
Please either format your code or (better!) link to your submission - the forum software has mangled it and it won’t compile! 
Also - what Problem are you trying to solve?

Why this is getting SIGABRT Error? It works fine for single test case.

int *ar = new int(N);
creates a single int, with value N, on the heap. You probably meant:
int *ar = new int[N];
(yet another reason to use vectors :))

I am getting SIGABRT i tried a lot of different ways to fix still i cant fix it
#include
#include
#include
#include
#include
using namespace std;
int main(){
ios::sync_with_stdio(0);
cin.tie(0);
long long t,n,k,l;
cin>>t;
map<long long,long long>player;
while(t--){
player.clear();
cin>>n>>k>>l;
if((n-k)==l){
cout<<-1<<endl;
continue;
}
vector<long long> vi(n);
for(int i=1;i<=k;i++){
vi[i]=i;
player[i]++;
}
int p=k+1;
for(int i=p;i<=n;i++){
for(int j=1;j<=k;j++){
if(player[j]<l && (i!=j+1) ){
vi[i]=j;
}
}
}
for(int i=1;i<=vi.size();i++){
cout<<vi[i]<<" ";
}
cout<<endl;
}
}
Here’s your solution, just copy pasted from your submission.
I guess I found the error.
You are trying to access invalid memory location. (Mentioned ‘here’ as a comment).
#include <bits/stdc++.h>
using namespace std;
int main()
{
int i,n,k,c=0;
cin >> n >> k;
string s[k+1]; int a[k+1]={0};
fflush(stdin);
for(i=1;i<=k;i++)
getline(cin,s[i]);
for(i=1;i<=k;i++){
if(s[i]== "CLOSEALL"){
a[k+1]={0}; //here
cout << 0 << endl;
}
else {
if(a[stoi(s[i].substr(6,7))]==0){
a[stoi(s[i].substr(6,7))]=1;
++c;
}
else{
a[stoi(s[i].substr(6,7))]=0;
--c;
}
if(c<0) c=0;
cout << c << endl;
}
}
return 0;
}

I tried to run it by commenting that part and I still get the error.
In that part I am just Initalizing. Here is the more elaborate error
“terminate called after throwing an instance of ‘std::out_of_range’
what(): basic_string::substr: __pos (which is 6) > this->size() (which is 0)”.
thanks bro
Thank you
