[leetcode greedy]455. Assign Cookies

Posted 2020-09-03 wilderness

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.

题意：把m块饼干分给n个孩子，每块饼干的尺寸为mi，每个孩子的要求尺寸为ni，最多可以使几个孩子满足？

思路：

排序，目标只分饼干，从小到大遍历饼干，只要有某个饼干可以满足某个孩子，就立马把饼干分出去，如果某块饼干不能满足最小的需求尺寸，立马舍弃这块饼干

 7             if i == len(g):
 8                 break
 9             if si >= g[i]:
10                 n += 1
11                 i += 1
12         return n
