这道题目上来也是没什么思路啊

这道题目不好想啊，贪心很巧妙

class Solution {
public:
    int candy(vector<int>& ratings) {
        vector<int> candyVec(ratings.size(), 1);
        // 从前向后 
        for (int i = 1; i < ratings.size(); i++) {
            if (ratings[i] > ratings[i - 1]) candyVec[i] = candyVec[i - 1] + 1;
        }
        // 从后向前
        for (int i = ratings.size() - 2; i >= 0; i--) {
            if (ratings[i] > ratings[i + 1] && candyVec[i] < candyVec[i + 1] + 1) {
                candyVec[i] = candyVec[i + 1] + 1;
            }
        }
        // 统计结果 
        int result = 0;
        for (int i = 0; i < candyVec.size(); i++) result += candyVec[i];
        return result;
    }
};
