It is a sweltering summer day, and a boy wants to buy some ice cream bars.

At 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.

**Example 1:**

**Input:** costs = [1,3,2,4,1], coins = 7

**Output:** 4

**Explanation:** The boy can buy ice cream bars at indices 0,1,2,4 for a total price of 1 + 3 + 2 + 1 = 7.

**Example 2:**

**Input:** costs = [10,6,8,7,7,8], coins = 5

**Output:** 0

**Explanation:** The boy cannot afford any of the ice cream bars.

**Example 3:**

**Input:** costs = [1,6,3,1,2,5], coins = 20

**Output:** 6

**Explanation:** The boy can buy all the ice cream bars for a total price of 1 + 6 + 3 + 1 + 2 + 5 = 18.

**Constraints:**

*   `costs.length == n`
*   1 <= n <= 105
*   1 <= costs[i] <= 105
*   1 <= coins <= 108
