C solution:
void solve(){
int n;
cin>>n;
string s;
cin>>s;
map mp;
for(auto &i: s) mp[i]++;
priority_queue pq;
for(auto i: mp){
pq.push({ i.second, i.first });
}
vector a;
int num = pq.top().first;
char ch = pq.top().ss;
pq.pop();
forn(i,0,num){
string s;
s += ch;
a.pb(s);
}

int ind = 0;
while(!pq.empty()){
char ch = pq.top().ss;
int num = pq.top().ff;
while(num > 0){
a[ind] += ch;
num--;
ind = (ind + 1) % (a.size());
}
pq.pop();
}
string ans = "";
for(auto i: a) ans += i;
cout m;
int secMex = 0;
while(x--){
int n;
cin>>n;
set s;
forn(i,0,n) {
int x; cin>>x;
s.insert(x);
}
int num = 0;
int cnt = 0;
while(cnt < 2){
if(s.count(num) == 0){
s.insert(num);
secMex = max(secMex, num);
cnt++;
}
num++;
}
}
if(m < secMex) {
int ans = secMex*(m + 1);
cout
