485. Max Consecutive Ones

题目：

Given a binary array, find the maximum number of consecutive 1s in this array.

Example 1:

Input: [1,1,0,1,1,1]
Output: 3
Explanation: The first two digits or the last three digits are consecutive 1s.
    The maximum number of consecutive 1s is 3.

 

Note:

• The input array will only contain 0 and 1.
• The length of input array is a positive integer and will not exceed 10,000

给你一个二位数列表，求出列表最大的1连续的数目

思路：

很简单的列表遍历，要注意的就是最后一次遍历的值也要进行比较

 

结果：

class Solution(object):
    def findMaxConsecutiveOnes(self, nums):
        """
        :type nums: List[int]
        :rtype: int
        """
        max_num = 0
        statistics = 0
        # 遍历列表
        for temp in nums:
            if temp == 1:
                statistics += 1
            else:
                if statistics > max_num:
                    max_num = statistics
                statistics = 0
        # 保证最后一遍也能进行比较
        if statistics > max_num:
            max_num = statistics
        return max_num
