My issue
include
using namespace std;
int main() {
// your code goes here
int t;
cin>>t;
while (t–) {
int n;
cin>>n;
string s;
cin>>s;
int ct1 = 0;
int ct2 = 0;
for (auto i:s) {
if (i == ‘0’) ct1++;
else ct2++;
}
if (n % 2 == 0) {
if (ct2 % 2 == 0 && ct1 % 2 == 0) cout<<"YES"<<endl;
else cout<<"NO"<<endl;
}
else {
cout<<"YES"<<endl;
}
}
return 0;
