Can Place Flowers
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 flowerbed containing 0's and 1's, where 0 means empty and 1 means not empty, and an integer n, return true if n new flowers can be planted in the flowerbed without violating the no-adjacent-flowers rule and false otherwise.
Example 1
Input
flowerbed = [1,0,0,0,1], n = 1Output
trueOne new flower can be planted in the middle empty plot without being adjacent to another flower.
Example 2
Input
flowerbed = [1,0,0,0,1], n = 2Output
falseThere is only one valid place to plant a new flower, so two flowers cannot be planted.
Constraints
- 1 <= flowerbed.length <= 2 * 10^4
- flowerbed[i] is 0 or 1.
- There are no two adjacent flowers in flowerbed.
- 0 <= n <= flowerbed.length
