It is a sweltering summer day, and a boy wants to buy some ice cream bars.
\r\n\r\nAt the store, there are n ice cream bars. You are given an array costs of length n, where costs[i] is the price of the ith ice cream bar in coins. The boy initially has coins coins to spend, and he wants to buy as many ice cream bars as possible.
Return the maximum number of ice cream bars the boy can buy with coins coins.
Note: The boy can buy the ice cream bars in any order.
\r\n\r\n\r\n
Example 1:
\r\n\r\n\r\nInput: costs = [1,3,2,4,1], coins = 7\r\nOutput: 4\r\nExplanation: The boy can buy ice cream bars at indices 0,1,2,4 for a total price of 1 + 3 + 2 + 1 = 7.\r\n\r\n\r\n
Example 2:
\r\n\r\n\r\nInput: costs = [10,6,8,7,7,8], coins = 5\r\nOutput: 0\r\nExplanation: The boy cannot afford any of the ice cream bars.\r\n\r\n\r\n
Example 3:
\r\n\r\n\r\nInput: costs = [1,6,3,1,2,5], coins = 20\r\nOutput: 6\r\nExplanation: The boy can buy all the ice cream bars for a total price of 1 + 6 + 3 + 1 + 2 + 5 = 18.\r\n\r\n\r\n
\r\n
Constraints:
\r\n\r\ncosts.length == n1 <= n <= 1051 <= costs[i] <= 1051 <= coins <= 108夏日炎炎，小男孩 Tony 想买一些雪糕消消暑。
\n\n商店中新到 n 支雪糕，用长度为 n 的数组 costs 表示雪糕的定价，其中 costs[i] 表示第 i 支雪糕的现金价格。Tony 一共有 coins 现金可以用于消费，他想要买尽可能多的雪糕。
给你价格数组 costs 和现金量 coins ，请你计算并返回 Tony 用 coins 现金能够买到的雪糕的 最大数量 。
注意：Tony 可以按任意顺序购买雪糕。
\n\n\n\n
示例 1：
\n\n输入：costs = [1,3,2,4,1], coins = 7\n输出：4\n解释：Tony 可以买下标为 0、1、2、4 的雪糕，总价为 1 + 3 + 2 + 1 = 7\n\n\n
示例 2：
\n\n输入：costs = [10,6,8,7,7,8], coins = 5\n输出：0\n解释：Tony 没有足够的钱买任何一支雪糕。\n\n\n
示例 3：
\n\n输入：costs = [1,6,3,1,2,5], coins = 20\n输出：6\n解释：Tony 可以买下所有的雪糕，总价为 1 + 6 + 3 + 1 + 2 + 5 = 18 。\n\n\n
