475 - Heaters.<p>Medium</p> <p>Winter is coming! During the contest, your first job is to design a standard heater with a fixed warm radius to warm all the houses.</p> <p>Every house can be warmed, as long as the house is within the heater&rsquo;s warm radius range.</p> <p>Given the positions of <code>houses</code> and <code>heaters</code> on a horizontal line, return <em>the minimum radius standard of heaters so that those heaters could cover all houses.</em></p> <p><strong>Notice</strong> that all the <code>heaters</code> follow your radius standard, and the warm radius will the same.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> houses = [1,2,3], heaters = [2]</p> <p><strong>Output:</strong> 1</p> <p><strong>Explanation:</strong> The only heater was placed in the position 2, and if we use the radius 1 standard, then all the houses can be warmed.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> houses = [1,2,3,4], heaters = [1,4]</p> <p><strong>Output:</strong> 1</p> <p><strong>Explanation:</strong> The two heater was placed in the position 1 and 4. We need to use radius 1 standard, then all the houses can be warmed.</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> houses = [1,5], heaters = [2]</p> <p><strong>Output:</strong> 3</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= houses.length, heaters.length <= 3 * 10<sup>4</sup></code></li> <li><code>1 <= houses[i], heaters[i] <= 10<sup>9</sup></code></li> </ul>
