就直接sort 看能買多少買多少 貪心算法

就這樣 不知道為啥medium

class Solution:
    def maxIceCream(self, costs: List[int], coins: int) -> int:
        
        
        costs.sort()
        
        ans=0
        
        for i in costs:
            if coins-i>=0:
                coins-=i
                ans+=1
            else:
                break
