Solution: Can Place Flowers

Explore how to use a greedy algorithm to plant a specified number of flowers in a flowerbed while adhering to the rule that no two flowers can be planted next to each other. This lesson teaches you to maximize flower placement by checking neighbors efficiently and returning true when all flowers fit without conflict.

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 ...
