2136. 全部开花的最早一天 - 力扣(LeetCode)
简单的贪心然后结构体排序(也可以创建数组记录位置访问)
- class Solution {
- public:
- struct node
- {
- int id, p, g;
- node(int a,int b, int c) : id(a), p(b), g(c){};
- };
- int earliestFullBloom(vector<int>& plantTime, vector<int>& growTime)
- {
- vector
v; - int n = plantTime.size();
- for(int i = 0; i < n; i++)
- v.emplace_back(i,plantTime[i],growTime[i]);
- sort(v.begin(),v.end(),[&](auto x,auto y) {return x.g > y.g;});
- int ans = 0, pre = 0;
- for(auto x : v)
- {
- ans = max(ans, pre + x.p + x.g);
- pre += x.p;
- }
- return ans;
- }
- };
