Assign Cookies.java

/*
	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: 

		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.
