605. Can Place Flowers

Leetcode Solutions

Single Scan Approach

  1. Initialize count to 0 to keep track of the number of flowers that can be planted.
  2. Iterate through each plot in the flowerbed array.
  3. For each plot, check if it is empty (i.e., flowerbed[i] == 0).
  4. If the plot is at the beginning or end of the array, check only one adjacent plot. Otherwise, check both adjacent plots.
  5. If the adjacent plots are also empty (or if it's the first or last plot with one empty adjacent plot), increment count and mark the current plot as planted by setting flowerbed[i] = 1.
  6. If count becomes equal to or greater than n, return true.
  7. After the loop, if count is less than n, return false.
