Max Consecutive Ones

Posted 2020-10-05 白常福

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

 

分析：计算1连续出现的最大次数。

思路：遍历统计次数，记录下连续出现的次数即可。

JAVA CODE

class Solution {
    public int findMaxConsecutiveOnes(int[] nums) {
        int times = 0, maxTimes = 0;
        for(int i = 0; i < nums.length; i++){
            if(nums[i] == 0){
                maxTimes = maxTimes > times ? maxTimes : times;
                times = 0;
            }else{
                times++;
            }
        }
        return maxTimes = maxTimes > times ? maxTimes : times;
    }
}
