题目描述:
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.
The maximum number of consecutive 1s is 3.
Note:
- The input array will only contain
0and1. - 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,计算数组中出现的最大连续1的个数。
注意:
- 输入数组只包含0和1
- 数组长度是正整数并且不会超过10000
解题思路:
一趟遍历+计数器
Python代码:
class Solution(object):
def findMaxConsecutiveOnes(self, nums):
"""
:type nums: List[int]
:rtype: int
"""
ans = cnt = 0
for n in nums:
if n == 1:
cnt += 1
ans = max(ans, cnt)
else:
cnt = 0
return ans
