自己看着舒服就行，不用刻意改

可读性高就可以不改（比如你这段

觉得可以。
交题解这格式可以

@[BWsha2k](/user/666114) 没有必要，个人看着觉得 ok

没有必要
~~但是后期不压点行，根本写不了调不了一点（）~~
不过你现在没有影响

改成这样：
```cpp
#include <iostream>
#include <string>
using namespace std;
int T, n, q, o, p, cnt;
string s, t;
char c;
void solve() {
cnt = 0;
cin >> s >> t;
for (int i = 0; i < n; i++) {
cnt += (s[i] != t[i]);
}
cout << (!cnt ? "Yes" : "No") << '\n';
for (int i = 0; i < q; i++) {
cin >> o >> p >> c;
p--;
cnt -= (s[p] != t[p]);
!o ? s[p] = c : t[p] = c;
cnt += (s[p] != t[p]);
cout << (!cnt ? "Yes" : "No") << '\n';
}
return;
}
void getinit() {
for (cin >> T; T--;) {
cin >> n >> q;
solve();
}
}
int main() {
ios::sync_with_stdio(false), cin.tie(0);
getinit();
return 0;
}
```
