668 - Kth Smallest Number in Multiplication Table.<p>Hard</p> <p>Nearly everyone has used the <a href="https://en.wikipedia.org/wiki/Multiplication_table" target="_top">Multiplication Table</a>. The multiplication table of size <code>m x n</code> is an integer matrix <code>mat</code> where <code>mat[i][j] == i * j</code> ( <strong>1-indexed</strong> ).</p> <p>Given three integers <code>m</code>, <code>n</code>, and <code>k</code>, return <em>the</em> <code>k<sup>th</sup></code> <em>smallest element in the</em> <code>m x n</code> <em>multiplication table</em>.</p> <p><strong>Example 1:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2021/05/02/multtable1-grid.jpg" alt="" /></p> <p><strong>Input:</strong> m = 3, n = 3, k = 5</p> <p><strong>Output:</strong> 3</p> <p><strong>Explanation:</strong> The 5<sup>th</sup> smallest number is 3.</p> <p><strong>Example 2:</strong></p> <p><img src="https://assets.leetcode.com/uploads/2021/05/02/multtable2-grid.jpg" alt="" /></p> <p><strong>Input:</strong> m = 2, n = 3, k = 6</p> <p><strong>Output:</strong> 6</p> <p><strong>Explanation:</strong> The 6<sup>th</sup> smallest number is 6.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= m, n <= 3 * 10<sup>4</sup></code></li> <li><code>1 <= k <= m * n</code></li> </ul>
