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

解题方案

思路 1
**- 时间复杂度: O(N)**- 空间复杂度: O(N)**

  • 使用temp保存每个0之间的差值
  • 找出最大的差值即可

    for(var i =0;i<nums.length;i++){
        nums[i]===0?temp=0:temp++;
        max = Math.max(temp,max);
    }
