455. Assign Cookies

排序+双指针+贪心

class Solution {
public:
    int findContentChildren(vector<int>& g, vector<int>& s) {
        int res = 0;
        sort(g.begin(),g.end());
        sort(s.begin(),s.end());
        for(int i = 0,j = 0;i<g.size()&&j<s.size();i++){
            while(j<s.size() && s[j]<g[i] ){
                j++;
            }
            if(j == s.size())
                break;
            res++;
            j++;
        }
        return res;
    }
};

2410. Maximum Matching of Players With Trainers

这道题和上面的是一模一样的。

class Solution {
public:
    int matchPlayersAndTrainers(vector<int>& players, vector<int>& trainers) {
        sort(players.begin(),players.end());
        sort(trainers.begin(),trainers.end());
        int res = 0;
        for(int i = 0,j = 0;i<players.size()&&j<trainers.size();i++){
            while(j<trainers.size() && trainers[j]<players[i]){
                j++;
            }
            if(j == trainers.size())
                break;
            res++;
            j++;
        }
        return res;
    }
};
