while True:

    try:
        n = int(input())
        bit_num = bin(n).lstrip('0b')
        num_length = len(bit_num)
        dp = [0 for i in range(num_length)]
        if bit_num[0] == '1':
            dp[0] = 1
        for i in range(1, num_length):
            if bit_num[i] == '1' and bit_num[i-1] == '1':
                dp[i] = dp[i-1] + 1
            elif bit_num[i] == '1' and bit_num[i - 1] == '0':
                dp[i] = 1
            else:
                dp[i] = dp[i-1]
        print(max(dp))

    except:
        break

伪动态分配，多加了一个条件，遇到01就设状态空间值为1，然后求所有状态空间的最大值，即为所需结果。
