<p><strong>Explanation:</strong> Alice can pick up <code>3</code> ones in <code>3</code> moves, if Alice performs the following actions in each move when standing at <code>aliceIndex == 1</code>:</p>

<li> At the start of the game Alice picks up the one and <code>nums[1]</code> becomes <code>0</code>. <code>nums</code> becomes <code>[1,<strong><u>1</u></strong>,1,0,0,1,1,0,0,1]</code>.</li>

<li>Select <code>x == 2</code> and <code>y == 1</code>, and perform an action of the second type. <code>nums</code> becomes <code>[1,<strong><u>1</u></strong>,0,0,0,1,1,0,0,1]</code>.
