class Solution:
    # Time: O(n log n + m log m)
    # Space: O(1) excluding sort space
    def find_content_children(self, g: list[int], s: list[int]) -> int:
        g.sort()
        s.sort()

        child = 0
        for cookie in s:
            if child < len(g) and cookie >= g[child]:
                child += 1
        return child
