Share Assume you are an awesome parent and want to give your children some cookies. But, you should give each child at most one cookie. Each child i has a greed factor gi, which is the minimum size of a cookie that the child will be content with; and each cookie j has a size sj. If sj >= gi, we can assign the cookie j to the child i, and the child i will be content. Your goal is to maximize the number of your content children and output the maximum number.

Note: You may assume the greed factor is always positive. You cannot assign more than one cookie to one child.

Example 1: Input: [1,2,3], [1,1]

Output: 1

Explanation: You have 3 children and 2 cookies. The greed factors of 3 children are 1, 2, 3. And even though you have 2 cookies, since their size is both 1, you could only make the child whose greed factor is 1 content. You need to output 1. Example 2: Input: [1,2], [1,2,3]

Output: 2

Explanation: You have 2 children and 3 cookies. The greed factors of 2 children are 1, 2. You have 3 cookies and their sizes are big enough to gratify all of the children, You need to output 2.

思路：貪心算法，只要s最大值知足大於g最大值，統計數據count+=1

代碼：python3

class Solution:
    def findContentChildren(self, g: List[int], s: List[int]) -> int:
        g.sort(reverse=True)
        s.sort()
        print(g)
        num=0
        j=len(s)-1
        for index,value in enumerate(g):
            if j>=0 and value<=s[j] :
                num+=1
                j-=1
            else:
            	pass
        return num
