<p>Given two straight line segments (represented as a start point and an end point), compute the point of intersection, if any. If there&#39;s no intersection, return an empty array.</p>

The absolute error should not exceed 10^-6. If there are more than one intersections, return the one with smallest X axis value. If there are more than one intersections that have same X axis value, return the one with smallest Y axis value.



<p><strong>Example 1: </strong></p>



<pre>

<strong>Input: </strong>

line1 = {0, 0}, {1, 0}

line2 = {1, 1}, {0, -1}

<strong>Output: </strong> {0.5, 0}

</pre>



<p><strong>Example 2: </strong></p>



<pre>

<strong>Input: </strong>

line1 = {0, 0}, {3, 3}

line2 = {1, 1}, {2, 2}

<strong>Output: </strong> {1, 1}

</pre>



<p><strong>Example 3: </strong></p>



<pre>

<strong>Input: </strong>

line1 = {0, 0}, {1, 1}

line2 = {1, 0}, {2, 1}

<strong>Output: </strong> {}  (no intersection)

</pre>
