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.

- Are the inputs two list(int), one for greed factor and the other for cookie size?
- Yes

- Are the inputs are sorted increasing order?
- No

- Can we change inputs themselves, or do we need to make a copy?
- You can change them

- Is the output an int?
- Yes

- Is the greed factor always >= 1?
- Yes

- Can we assume the inputs are valid?
- No, check for None

- Can we assume this fits memory?
- Yes

* None input -> TypeError [1, 2, 3], [1, 1] -> 1 [1, 2], [1, 2, 3] -> 2 [7, 8, 9, 10], [5, 6, 7, 8] -> 2

Refer to the Solution Notebook. If you are stuck and need a hint, the solution notebook's algorithm discussion might be a good place to start.

In [ ]:

```
class Solution(object):
def find_content_children(self, g, s):
# TODO: Implement me
pass
```

**The following unit test is expected to fail until you solve the challenge.**

```
# %load test_assign_cookie.py
import unittest
class TestAssignCookie(unittest.TestCase):
def test_assign_cookie(self):
solution = Solution()
self.assertRaises(TypeError, solution.find_content_children, None, None)
self.assertEqual(solution.find_content_children([1, 2, 3],
[1, 1]), 1)
self.assertEqual(solution.find_content_children([1, 2],
[1, 2, 3]), 2)
self.assertEqual(solution.find_content_children([7, 8, 9, 10],
[5, 6, 7, 8]), 2)
print('Success: test_find_content_children')
def main():
test = TestAssignCookie()
test.test_assign_cookie()
