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:

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:

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
