1518 - Water Bottles.<p>Easy</p> <p>There are <code>numBottles</code> water bottles that are initially full of water. You can exchange <code>numExchange</code> empty water bottles from the market with one full water bottle.</p> <p>The operation of drinking a full water bottle turns it into an empty bottle.</p> <p>Given the two integers <code>numBottles</code> and <code>numExchange</code>, return <em>the <strong>maximum</strong> number of water bottles you can drink</em>.</p> <p><strong>Example 1:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2020/07/01/sample_1_1875.png" alt="" /></p> <p><strong>Input:</strong> numBottles = 9, numExchange = 3</p> <p><strong>Output:</strong> 13</p> <p><strong>Explanation:</strong> You can exchange 3 empty bottles to get 1 full water bottle. Number of water bottles you can drink: 9 + 3 + 1 = 13.</p> <p><strong>Example 2:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2020/07/01/sample_2_1875.png" alt="" /></p> <p><strong>Input:</strong> numBottles = 15, numExchange = 4</p> <p><strong>Output:</strong> 19</p> <p><strong>Explanation:</strong> You can exchange 4 empty bottles to get 1 full water bottle. Number of water bottles you can drink: 15 + 3 + 1 = 19.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= numBottles <= 100</code></li> <li><code>2 <= numExchange <= 100</code></li> </ul>
