# [1004. Max Consecutive Ones III](https://leetcode.com/problems/max-consecutive-ones-iii/)
|
||
|
||
## 题目
|
||
|
||
Given an array A of 0s and 1s, we may change up to K values from 0 to 1.
|
||
|
||
Return the length of the longest (contiguous) subarray that contains only 1s.
|
||
|
||
|
||
Example 1:
|
||
|
||
```c
|
||
Input: A = [1,1,1,0,0,0,1,1,1,1,0], K = 2
|
||
Output: 6
|
||
Explanation:
|
||
[1,1,1,0,0,1,1,1,1,1,1]
|
||
Bolded numbers were flipped from 0 to 1. The longest subarray is underlined.
|
||
```
|
||
|
||
Example 2:
|
||
|
||
```c
|
||
Input: A = [0,0,1,1,0,0,1,1,1,0,1,1,0,0,0,1,1,1,1], K = 3
|
||
Output: 10
|
||
Explanation:
|
||
[0,0,1,1,1,1,1,1,1,1,1,1,0,0,0,1,1,1,1]
|
||
Bolded numbers were flipped from 0 to 1. The longest subarray is underlined.
|
||
```
|
||
|
||
|
||
Note:
|
||
|
||
- 1 <= A.length <= 20000
|
||
- 0 <= K <= A.length
|
||
- A[i] is 0 or 1
|
||
|
||
|
||
## 题目大意
|
||
|
||
这道题考察的是滑动窗口的问题。
|
||
|
||
给出一个数组，数组中元素只包含 0 和 1 。再给一个 K，代表能将 0 变成 1 的次数。要求出经过变换以后，1 连续的最长长度。
|
||
|
||
## 解题思路
|
||
|
||
按照滑动窗口的思路处理即可，不断的更新和维护最大长度。
