题解 | 求最大连续bit数

#include <iostream>
using namespace std;

int main() {
    int a;

    while (cin >> a) {
        int count = 0;
        int maxLength = 0;
        int b;
        for (int i = 0; i <= 19; i++) {
            b = a & (1 << i);
            if (b) {
                count++;
            } else {
                maxLength = count > maxLength ? count : maxLength;
                count = 0;
            }

        }

        cout << maxLength << endl;
    }
}
