public class Solution extends Object
1802 - Maximum Value at a Given Index in a Bounded Array.<p>Medium</p> <p>You are given three positive integers: <code>n</code>, <code>index</code>, and <code>maxSum</code>. You want to construct an array <code>nums</code> ( <strong>0-indexed</strong> ) that satisfies the following conditions:</p> <ul> <li><code>nums.length == n</code></li> <li><code>nums[i]</code> is a <strong>positive</strong> integer where <code>0 <= i < n</code>.</li> <li><code>abs(nums[i] - nums[i+1]) <= 1</code> where <code>0 <= i < n-1</code>.</li> <li>The sum of all the elements of <code>nums</code> does not exceed <code>maxSum</code>.</li> <li><code>nums[index]</code> is <strong>maximized</strong>.</li> </ul> <p>Return <code>nums[index]</code> <em>of the constructed array</em>.</p> <p>Note that <code>abs(x)</code> equals <code>x</code> if <code>x >= 0</code>, and <code>-x</code> otherwise.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> n = 4, index = 2, maxSum = 6</p> <p><strong>Output:</strong> 2</p> <p><strong>Explanation:</strong> nums = [1,2, <strong>2</strong> ,1] is one array that satisfies all the conditions. There are no arrays that satisfy all the conditions and have nums[2] == 3, so 2 is the maximum nums[2].</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> n = 6, index = 1, maxSum = 10</p> <p><strong>Output:</strong> 3</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= n <= maxSum <= 10<sup>9</sup></code></li> <li><code>0 <= index < n</code></li> </ul>
