从十进制转换为二进制时查找连续 1 的最大数量

Question

为什么我无法获得 6 和倍数的值？

我哪里出错了？

import java.util.*;
public class Solution {
    public static void main(String[] args) {
        int m = 0, temp;
        int arr[] = new int[5];
        int flag = 0;
        int n = scanner.nextInt();
        scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
        while (n > 0) {
            int rem = n % 2;

            if (rem > 0) {
                flag = flag + 1;
            } else {
                if (flag > 0) {
                    arr[m] = flag;
                    m = m + 1;
                }
                flag = 0;

            }
            n = n / 2;
        }
        for (int i = 0; i < arr.length; i++) {
            for (int j = i + 1; j < arr.length; j++) {
                if (arr[i] > arr[j]) {
                    temp = arr[i];
                    arr[i] = arr[j];
                    arr[j] = temp;
                }
            }
        }

        for (int i = 0; i < arr.length; i++) {
            System.out.println(arr[i]);
        }
        scanner.close();
    }
}
