## 1088. Confusing Number II (Hard)
13+
14+
<p>We can rotate digits by 180 degrees to form new digits. When 0, 1, 6, 8, 9 are rotated 180 degrees, they become 0, 1, 9, 8, 6 respectively. When 2, 3, 4, 5 and 7 are rotated 180 degrees, they become invalid.</p>
15+
16+
<p>A <em>confusing number</em> is a number that when rotated 180 degrees becomes a <strong>different</strong> number with each digit valid.(Note that the rotated number can be greater than the original number.)</p>
17+
18+
<p>Given a positive integer <code>N</code>, return the number of confusing numbers between <code>1</code> and <code>N</code>&nbsp;inclusive.</p>
19+

<strong>Input: </strong><span id="example-input-1-1">20</span>
26+
<strong>Output: </strong><span id="example-output-1">6</span>
27+
<strong>Explanation: </strong>
28+
The confusing numbers are [6,9,10,16,18,19].
29+
6 converts to 9.
30+
9 converts to 6.
31+
10 converts to 01 which is just 1.
32+
16 converts to 91.
33+
18 converts to 81.
