605. Can Place Flowers
题目：
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 be planted in it without violating the no-adjacent-flowers rule.
Example 1:
Input: flowerbed = [1,0,0,0,1], n = 1 Output: True
Example 2:
Input: flowerbed = [1,0,0,0,1], n = 2 Output: False
Note:
思路：
本题，只要就算可以插花的个数，每连续三个0可以插一朵花，但是要注意首尾为0的特殊情况
代码：
class Solution {
public:
bool canPlaceFlowers(vector<int>& flowerbed, int n) {
int i = 0;
while(i<flowerbed.size())
{
if(flowerbed[i]==0&&(i==0||flowerbed[i-1]==0)&&(i==flowerbed.size()-1||flowerbed[i+1]==0))
{
n--;
flowerbed[i] = 1;
}
i++;
}
return n<1?true:false;
}
};
