#include <bits/stdc++.h>
using namespace std;
using i64 = long long;
constexpr int maxn = 500000 + 10;
int p[maxn][2];
void solve()
{
string s;
cin >> s;
int n = s.size();
p[n][0] = p[n][1] = n;
for (int i=n-1;i>=0;--i)
{
p[i][0] = p[i + 1][0];
p[i][1] = p[i + 1][1];
p[i][s[i] == 'R'] = i;
}
int m;
cin >> m;
while (m--)
{
string t;
cin >> t;
if (t[0] == 'R' && s[0] == 'L' || t.back() == 'L' && s.back() == 'R') cout << "NO\n";
else
{
int x = -1;
for (char c : t)
{
x = p[x + 1][c == 'R'];
if (x == n) break;
}
cout << (x == n ? "NO\n" : "YES\n");
}
}
}
int main()
{
ios::sync_with_stdio(0);
cin.tie(0);
int t;
cin >> t;
while (t--) solve();
return 0;
}
这程序好像有点Bug，我给组数据试试？
