<h2><a href="https://leetcode.com/problems/determine-if-a-cell-is-reachable-at-a-given-time/">2849. Determine if a Cell Is Reachable at a Given Time</a></h2><h3>Medium</h3><hr><div><p>You are given four integers <code>sx</code>, <code>sy</code>, <code>fx</code>, <code>fy</code>, and a <strong>non-negative</strong> integer <code>t</code>.</p>

<p>In an infinite 2D grid, you start at the cell <code>(sx, sy)</code>. Each second, you <strong>must</strong> move to any of its adjacent cells.</p>

<p>Return <code>true</code> <em>if you can reach cell </em><code>(fx, fy)</code> <em>after<strong> exactly</strong></em> <code>t</code> <strong><em>seconds</em></strong>, <em>or</em> <code>false</code> <em>otherwise</em>.</p>

<p>A cell's <strong>adjacent cells</strong> are the 8 cells around it that share at least one corner with it. You can visit the same cell several times.</p>

<img alt="" src="https://assets.leetcode.com/uploads/2023/08/05/example2.svg" style="width: 443px; height: 243px;">
<pre><strong>Input:</strong> sx = 2, sy = 4, fx = 7, fy = 7, t = 6
<strong>Output:</strong> true
<strong>Explanation:</strong> Starting at cell (2, 4), we can reach cell (7, 7) in exactly 6 seconds by going through the cells depicted in the picture above.

<p><strong class="example">Example 2:</strong></p>
<img alt="" src="https://assets.leetcode.com/uploads/2023/08/05/example1.svg" style="width: 383px; height: 202px;">
<pre><strong>Input:</strong> sx = 3, sy = 1, fx = 7, fy = 3, t = 3
<strong>Output:</strong> false
<strong>Explanation:</strong> Starting at cell (3, 1), it takes at least 4 seconds to reach cell (7, 3) by going through the cells depicted in the picture above. Hence, we cannot reach cell (7, 3) at the third second.
