原题 前后两遍遍历
class Solution { public: int candy(vector<int> &ratings) { vector<int> res; int len = ratings.size(); for (int i = 0; i < len; i++) { res.push_back(1); } for (int j = 0; j < len; j++) { if (j > 0 && ratings[j] > ratings[j - 1]) { res[j] += res[j - 1]; } } for (int k = len - 1; k >= 0; --k) { if (k < len - 1 && ratings[k] > ratings[k + 1] && res[k] <= res[k+1]) { res[k] = res[k + 1]+1; } } int sum = 0; for (auto i : res) { cout<<i<<endl; sum += i; } return sum; } };转载于:https://www.cnblogs.com/ruoh3kou/p/9893425.html
