Solution: Can Place Flowers

Explore a greedy approach to solve the Can Place Flowers problem. Learn to efficiently check if n new flowers can be planted in a flowerbed array without violating adjacency rules. Understand how to implement the solution with optimal time and space complexity and apply this pattern in similar coding challenges.

We'll cover the following...

Statement

Given an integer list flowerbed, each element is either 00 (indicating an empty plot) or 11 (indicating a planted plot), and an integer n. Determine if n new flowers can be planted without violating the rule that no two flowers can be planted in adjacent plots. Return TRUE if it’s possible to plant all n flowers. Otherwise, return FALSE.

Constraints:

  • 1≤1\leq flowerbed.length ≤103\leq10^3 ...
