455. Assign Cookies

static int wing=[]()
{
    std::ios::sync_with_stdio(false);
    cin.tie(NULL);
    return 0;
}();

class Solution 
{
public:
    int findContentChildren(vector<int>& g, vector<int>& s) 
    {
        int szchild=g.size();
        int szcookies=s.size();
        if(szchild==0||szcookies==0)
            return 0;
        sort(g.begin(),g.end());
        sort(s.begin(),s.end());
        int indexchild=0,indexcookies=0;
        int count=0;
        while(indexchild<szchild&&indexcookies<szcookies)
        {
            if(s[indexcookies]>=g[indexchild])
            {
                count++;
                indexcookies++;
                indexchild++;
            }
            else
                indexcookies++;

        return count;
    }
};

排个序，俩数组元素扫描比较即可。
