LeetCode 485 Max Consecutive Ones 最大连续1的个数

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

题目描述

给定只含0，1的数组，在数组中返回连续的1的最大个数

解题思路

遍历一遍数组，用count记录当前1的个数，如果为1，则count加1，否则count为0，num记录现有连续1的最大个数。

/* C++ */
class Solution {
public:
    int findMaxConsecutiveOnes(vector<int>& nums) {
        if(nums.size() == 0) return 0;
        int count = 0;
        int num = 0;
        for(int i = 0;i < nums.size(); i++){
            if(nums[i] == 1)
                count++;
            else{

                count = 0;
            }
             num = max(num,count);
        }
        return num;

    }
};
