The robot receives an array of integers <code>commands</code>, which represents a sequence of moves that it needs to execute. There are only three possible types of instructions the robot can receive:</p>\n\n<ul>\n\t<li><code>-2</code>: Turn left <code>90</code> degrees.</li>\n\t<li><code>-1</code>: Turn right <code>90</code> degrees.</li>\n\t<li><code>1 &lt;= k &lt;= 9</code>: Move forward <code>k</code> units, one unit at a time.</li>\n</ul>\n\n<p>Some of the grid squares are <code>obstacles</code>. The <code>i<sup>th</sup></code> obstacle is at grid point <code>obstacles[i] = (x<sub>i</sub>, y<sub>i</sub>)</code>. If the robot runs into an obstacle, it will stay in its current location (on the block adjacent to the obstacle) and move onto the next command.</p>\n\n<p>Return the <strong>maximum squared Euclidean distance</strong> that the robot reaches at any point in its path (i.e. if the distance is <code>5</code>, return <code>25</code>).</p>\n\n<p><strong>Note:</strong></p>\n\n<ul>\n\t<li>There can be an obstacle at <code>(0, 0)</code>. If this happens, the robot will ignore the obstacle until it has moved off the origin. However, it will be unable to return to <code>(0, 0)</code> due to the obstacle.</li>\n\t<li>North means +Y direction.</li>\n\t<li>East means +X direction.</li>\n\t<li>South means -Y direction.</li>\n\t<li>West means -X direction.</li>\n</ul>\n\n<p>&nbsp;</p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<div class=\"example-block\">\n<p><strong>Input:</strong> <span class=\"example-io\">commands = [4,-1,3], obstacles = []</span></p>\n\n<p><strong>Output:</strong> <span class=\"example-io\">25</span></p>\n\n<p><strong>Explanation: </strong></p>\n\n<p>The robot starts at <code>(0, 0)</code>:</p>\n\n<ol>\n\t<li>Move north 4 units to <code>(0, 4)</code>.</li>\n\t<li>Turn right.</li>\n\t<li>Move east 3 units to <code>(3, 4)</code>.</li>\n</ol>\n\n<p>The furthest point the robot ever gets from the origin is <code>(3, 4)</code>, which squared is <code>3<sup>2</sup> + 4<sup>2 </sup>= 25</code> units away.</p>\n</div>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<div class=\"example-block\">\n<p><strong>Input:</strong> <span class=\"example-io\">commands = [4,-1,4,-2,4], obstacles = [[2,4]]</span></p>\n\n<p><strong>Output:</strong> <span class=\"example-io\">65</span></p>\n\n<p><strong>Explanation:</strong></p>\n\n<p>The robot starts at <code>(0, 0)</code>:</p>\n\n<ol>\n\t<li>Move north 4 units to <code>(0, 4)</code>.</li>\n\t<li>Turn right.</li>\n\t<li>Move east 1 unit and get blocked by the obstacle at <code>(2, 4)</code>, robot is at <code>(1, 4)</code>.</li>\n\t<li>Turn left.</li>\n\t<li>Move north 4 units to <code>(1, 8)</code>.</li>\n</ol>\n\n<p>The furthest point the robot ever gets from the origin is <code>(1, 8)</code>, which squared is <code>1<sup>2</sup> + 8<sup>2</sup> = 65</code> units away.</p>\n</div>\n\n<p><strong class=\"example\">Example 3:</strong></p>\n\n<div class=\"example-block\">\n<p><strong>Input:</strong> <span class=\"example-io\">commands = [6,-1,-1,6], obstacles = [[0,0]]</span></p>\n\n<p><strong>Output:</strong> <span class=\"example-io\">36</span></p>\n\n<p><strong>Explanation:</strong></p>\n\n<p>The robot starts at <code>(0, 0)</code>:</p>\n\n<ol>\n\t<li>Move north 6 units to <code>(0, 6)</code>.</li>\n\t<li>Turn right.</li>\n\t<li>Turn right.</li>\n\t<li>Move south 5 units and get blocked by the obstacle at <code>(0,0)</code>, robot is at <code>(0, 1)</code>.</li>\n</ol>\n\n<p>The furthest point the robot ever gets from the origin is <code>(0, 6)</code>, which squared is <code>6<sup>2</sup> = 36</code> units away.</p>\n</div>\n\n<p>&nbsp;</p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 &lt;= commands.length &lt;= 10<sup>4</sup></code></li>\n\t<li><code>commands[i]</code> is either <code>-2</code>, <code>-1</code>, or an integer in the range <code>[1, 9]</code>.</li>\n\t<li><code>0 &lt;= obstacles.length &lt;= 10<sup>4</sup></code></li>\n\t<li><code>-3 * 10<sup>4</sup> &lt;= x<sub>i</sub>, y<sub>i</sub> &lt;= 3 * 10<sup>4</sup></code></li>\n\t<li>The answer is guaranteed to be less than <code>2<sup>31</sup></code>.</li>\n</ul>\n",
