// this answer satisfies the question given in the link , but it still shows wrong why??
#include
using namespace std;
int n;
int y=0;
int main() {
int t;
cin>>t;

int c[1000000];

while(t--){
    cin>>n;
    int x=0;
    int i=0;
    while(n){
        c[i] = n%10;
        n/=10;
        i++;
        x++;
    }
   
   int a[10];
   int y=0;
   for(int i=0;i<x;i++){
       if(c[i]!=c[i-1]){
           a[y]=c[i];
           y++;
       }
   }
   
    for(int i=0;i<y;i++){
        cout<<a[i];
    }
    
    cout<<endl;
    
}
return 0;

}

I think that’s because the output should be in form of a number N and you are printing an array.
