There are numBottles water bottles that are initially full of water. You can exchange numExchange empty water bottles from the market with one full water bottle.
The operation of drinking a full water bottle turns it into an empty bottle.
\n\nGiven the two integers numBottles and numExchange, return the maximum number of water bottles you can drink.
\n
Example 1:
\n![\"\"](\"https://assets.leetcode.com/uploads/2020/07/01/sample_1_1875.png\")
\n\nInput: numBottles = 9, numExchange = 3\nOutput: 13\nExplanation: You can exchange 3 empty bottles to get 1 full water bottle.\nNumber of water bottles you can drink: 9 + 3 + 1 = 13.\n\n\n
Example 2:
\n![\"\"](\"https://assets.leetcode.com/uploads/2020/07/01/sample_2_1875.png\")
\n\nInput: numBottles = 15, numExchange = 4\nOutput: 19\nExplanation: You can exchange 4 empty bottles to get 1 full water bottle. \nNumber of water bottles you can drink: 15 + 3 + 1 = 19.\n\n\n
\n
Constraints:
\n\n1 <= numBottles <= 1002 <= numExchange <= 100超市正在促销，你可以用 numExchange 个空水瓶从超市兑换一瓶水。最开始，你一共购入了 numBottles 瓶水。
如果喝掉了水瓶中的水，那么水瓶就会变成空的。
\n\n给你两个整数 numBottles 和 numExchange ，返回你 最多 可以喝到多少瓶水。
\n\n
示例 1：
\n\n
\n输入：numBottles = 9, numExchange = 3\n输出：13\n解释：你可以用 3 个空瓶兑换 1 瓶水。\n所以最多能喝到 9 + 3 + 1 = 13 瓶水。\n\n\n示例 2：
\n\n![\"\"](\"https://assets.leetcode-cn.com/aliyun-lc-upload/uploads/2020/07/19/sample_2_1875.png\")
\n输入：numBottles = 15, numExchange = 4\n输出：19\n解释：你可以用 4 个空瓶兑换 1 瓶水。\n所以最多能喝到 15 + 3 + 1 = 19 瓶水。\n\n\n\n\n
