#include <bits/stdc++.h>
using i64 = long long;
void solve() {
int n;
std::cin >> n;
std::vector<int> s(n);
for (int i = 0; i < n; i++) {
std::cin >> s[i];
}
if (n < 10 || n > 13) {
std::cout << "No\n";
return;
}
std::sort(s.begin(), s.end());
if (s[0] != 1 || s[1] != 1) {
std::cout << "No\n";
return;
}
for (int i = 1; i < n - 1; i++) {
if (s[i] - s[i - 1] > 2) {
std::cout << "No\n";
return;
}
}
std::cout << "Yes\n";
}
int main() {
std::ios::sync_with_stdio(false);
std::cin.tie(nullptr);
int t;
std::cin >> t;
while (t--) {
solve();
}
return 0;
}
这程序好像有点Bug，我给组数据试试？
