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

求给定数组中最长连续1的个数。

这是一个连官方也懒得给solution的题目

但是还是要注意如果不是每次都判断是否当前连续1的个数超过记录的个数,就要在退出循环之后,返回结果之前再进行一次对当前连续1的个数和记录的最长连续1的个数的比较。

class Solution {
    public int findMaxConsecutiveOnes(int[] nums) {
        int result = 0;
        int now = 0;
        for (int elem : nums) {
            if (elem == 1) {
                ++now;
            } else {
                if (result < now) {
                    result = now;
                }
                now = 0;
            }
        }

        /* 最后再对now和result进行一次比较 */
        return now > result ? now : result;
    }
}
