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.

Running Tests

Example 1:

Input: flowerbed = [1,0,0,0,1], n = 1

Output: true

Explanation:

• Before planting any flowers: [1,0,0,0,1] → 🌻🟫🟫🟫🌻
• After planting n = 1 non-adjacent-flower: [1,0,1,0,1] → 🌻🟫🌻🟫🌻
• Bottom line: There is space to plant 1 flower without violating the no-adjacent-flowers rule. Therefore, the output is true.

Example 2:

Input: flowerbed = [1,0,0,0,1], n = 2

Output: false

Explanation:

• Before planting any flowers: [1,0,0,0,1] → 🌻🟫🟫🟫🌻
• After planting n = 2 non-adjacent-flowers: [1,0,1,0,1] → 🌻🟫🌻❌🌻
• Bottom line: It is only possible to plant 1 flower without violating the no-adjacent-flowers rule. Therefore, the output is false.

Example 3:

Input: flowerbed = [1,0,0,0,1,0,1,0,0,1], n = 2

Output: false

Explanation:

• Before planting any flowers: [1,0,0,0,1,0,1,0,0,1] → 🌻🟫🟫🟫🌻🟫🌻🟫🟫🌻
• After planting n = 2 non-adjacent-flowers: [1,0,1,0,1,0,1,0,0,1] → 🌻🟫🌻🟫🌻🟫🌻🟫❌🌻
• Bottom line: It is only possible to plant 1 flower without violating the no-adjacent-flowers rule. Therefore, the output is false.
