Suppose 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 - they would compete for water and both would die. Given a flowerbed (represented as an array containing 0 and 1, where 0 means empty and 1 means not empty), and a number n, return if n new flowers can b…

length = bed.count - 1

prv = bed[index - 1] if index > 0
nxt = bed[index + 1] if index < length
nxt = 0 if index == length
