#
# 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.
