 //Question 455. Assign Cookies
 /*
 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.
