当输入为 32 个 '0' 时，程序输出 12 个 0。（ ）

#include <iostream>
#include <cstring>
using namespace std;
string s;
int a[100];
int gen[13] = {1, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1};
int main() {
    cin >> s;
    for (int i = 0; i < 32; ++i) {
        a[i] = s[i] - '0';
    }
    for (int i = 32; i < 44; ++i) {
        a[i] = 0;
    }
    for (int i = 0; i < 32; ++i) {
        if (a[i] == 0) continue;
        for (int j = 0; j < 13; ++j) {
            a[i + j] ^= gen[j];
        }
    }
    for (int i = 32; i < 44; ++i) {
        cout << a[i];
    }
    cout << endl;
    return 0;
