+/***************************************************************************************************** 
+ *
+ * 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 i^th 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 <= 10^5
+ * 	1 <= costs[i] <= 10^5
+ * 	1 <= coins <= 10^8
