You have a long flowerbed in which some of the plots are planted, and some are not. However, flowers cannot be planted in adjacent plots.
Given an integer array
0 means empty and
1 means not empty, and an integer
n, return if
n new flowers can be planted in the
flowerbed without violating the no-adjacent-flowers rule.
Input: flowerbed = [1,0,0,0,1], n = 1 Output: true
Input: flowerbed = [1,0,0,0,1], n = 2 Output: false
1 <= flowerbed.length <= 2 * 104
0 <= n <= flowerbed.length
