• 描述：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.

• 分析：这道题是要最找到二进制串中连续最多的1的个数。

• 思路一：使用循环查找。

class Solution {
public:
    int findMaxConsecutiveOnes(vector<int>& nums) {
        int flag = 0;
        int res = 0;
        for (int i = 0; i < nums.size(); i++) {
            if (nums[i]) flag++;
            else flag = 0;
            if (flag > res) res = flag;
        }
        return res;
    }
};

• 思路二：python版

class Solution(object):
    def findMaxConsecutiveOnes(self, nums):
        """
        :type nums: List[int]
        :rtype: int
        """
        temp = 0
        res = 0
        for i in nums:
            if i == 1:
                temp = temp + 1
                res = max(res, temp)
            else:
                temp = 0
        return res
