455 Assign Cookies 分发饼干

假设你是一位很棒的家长,想要给你的孩子们一些小饼干。但是,每个孩子最多只能给一块饼干。对每个孩子 i ,都有一个胃口值 gi ,这是能让孩子们满足胃口的饼干的最小尺寸;并且每块饼干 j ,都有一个尺寸 sj 。如果 sj >= gi ,我们可以将这个饼干 j 分配给孩子 i ,这个孩子会得到满足。你的目标是尽可能满足越多数量的孩子,并输出这个最大数值。
注意:
你可以假设胃口值为正。
一个小朋友最多只能拥有一块饼干。
示例 1:
输入: [1,2,3], [1,1]
输出: 1
解释:
你有三个孩子和两块小饼干,3个孩子的胃口值分别是:1,2,3。
虽然你有两块小饼干,由于他们的尺寸都是1,你只能让胃口值是1的孩子满足。
所以你应该输出1。

示例 2:
输入: [1,2], [1,2,3]
输出: 2
解释:
你有两个孩子和三块小饼干,2个孩子的胃口值分别是1,2。
你拥有的饼干数量和尺寸都足以让所有孩子满足。
所以你应该输出2.

方法一:

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

方法二:

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