而且WA：提供的信息是把我输出的数n读为n+1了？？？ 以下是源码：```cpp

include <iostream>

using namespace std; int a[20005];

int main() { int n = 0; char t = '0'; char last = '0'; int p = 1; int N = 0; while (1) {

    t = getchar();

    if (t == '\n') {
        n = N;
        break;
    }

    if (t == last) {
        a[p]++;
    } else {
        a[++p]++;
        last = t;
    }
    N++;
}
for (int i = 1; i <= (n - 1) * (n + 1); i++) {
    t = getchar();

    if (t == '\n') {
        continue;
    }

    if (t == last) {
        a[p]++;
    } else {
        a[++p]++;
        last = t;
    }
}

cout << n << " ";
for (int i = 1; i <= p; i++) {
    cout << a[i] << " ";
}

}
