485. Max Consecutive Ones

题目

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

题目大意

给定一个二进制数组, 计算其中最大连续1的个数。

注意:

  • 输入的数组只包含 0 和 1。
  • 输入数组的长度是正整数,且不超过 10,000。

解题思路

  • 给定一个二进制数组, 计算其中最大连续1的个数。
  • 简单题。扫一遍数组,累计 1 的个数,动态维护最大的计数,最终输出即可。

代码

package leetcode func findMaxConsecutiveOnes(nums []int) int { maxCount, currentCount := 0, 0 for _, v := range nums { if v == 1 { currentCount++ } else { currentCount = 0 } if currentCount > maxCount { maxCount = currentCount } } return maxCount }
