leetcode 485. 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. ......
[LeetCode]485. Max Consecutive Ones 找到最大的连续的1的个数 题目描述 输入只有0和1的数组(长度为正整数,且<10000),找到最大的连续1的个数 比如[1,1,0,1,1,1],输出3 思路 遍历数组,统计当前连续个数curCount和最大连续值maxCount。If当前数组值为1,则curCount++;否则(值为0)比较curCount和max...
LeetCode题解之Max Consecutive Ones 1、题目描述 2、问题分析 遍历一次数组,以每个1 为起点向后数,数到0 时比较当前1的个数和最大1 的个数,然后将遍历的起点放到当前0 的后面。 3、代码 1intfindMaxConsecutiveOnes(vector<int>&nums) {2intresult =0;3if( nums.size() ==0)returnresult;45for(inti...
LeetCode: Max Consecutive Ones 这题最关键的是处理最开始连续1和最后连续1的方式,想到list一般在最前面加个node的处理方式,在最前面和最后面加0即可以很好地处理了 1publicclassSolution {2publicintfindMaxConsecutiveOnes(int[] nums) {3int[] newNums =newint[nums.length+2];4newNums[0] = 0;5new...
Leetcode之Max Consecutive Ones 问题 地址:https://leetcode.com/problems/max-consecutive-ones/description/)思路分析:这道题很简单吧,也没啥技巧,唯一可以注意的就是代码简洁的部分了,题目说的很清楚了,数组中只有0和1,遇到1的时候就累加,更新一下最大值,遇到0的时候计数器就重置为0 代码: ...
