（leetcode題解）Max Consecutive Ones

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

題意是在一個二進制數組中，找到此數組中連續1的最大數。

這個循環一遍記錄最大連續值便可，C++實現以下：

    int findMaxConsecutiveOnes(vector<int>& nums) {
        int count=0;
        int max=0;
        for(int i=0;i<nums.size();i++)
        {
            if(nums[i]==1)
            {
                count++;
            }
            else
            {
                count=0;
            }
            if(count>max)
                    max=count;
        }
        return max;
    }
