2566 - Maximum Difference by Remapping a Digit.<p>Easy</p>
<p>You are given an integer <code>num</code>. You know that Danny Mittal will sneakily <strong>remap</strong> one of the <code>10</code> possible digits (<code>0</code> to <code>9</code>) to another digit.</p>
<p>Return <em>the difference between the maximum and minimum</em>_ values Danny can make by remapping <strong>exactly</strong> <strong>one</strong> digit_ <em>in</em> <code>num</code>.</p>
<p><strong>Notes:</strong></p>
<ul>
<li>When Danny remaps a digit d1 to another digit d2, Danny replaces all occurrences of <code>d1</code> in <code>num</code> with <code>d2</code>.</li>
<li>Danny can remap a digit to itself, in which case <code>num</code> does not change.</li>
<li>Danny can remap different digits for obtaining minimum and maximum values respectively.</li>
<li>The resulting number after remapping can contain leading zeroes.</li>
<li>We mentioned “Danny Mittal” to congratulate him on being in the top 10 in Weekly Contest 326.</li>
</ul>
<p><strong>Example 1:</strong></p>
<p><strong>Input:</strong> num = 11891</p>
<p><strong>Output:</strong> 99009</p>
<p><strong>Explanation:</strong></p>
<p>To achieve the maximum value, Danny can remap the digit 1 to the digit 9 to yield 99899.</p>
<p>To achieve the minimum value, Danny can remap the digit 1 to the digit 0, yielding 890. The difference between these two numbers is 99009.</p>
<p><strong>Example 2:</strong></p>
<p><strong>Input:</strong> num = 90</p>
<p><strong>Output:</strong> 99</p>
<p><strong>Explanation:</strong></p>
<p>The maximum value that can be returned by the function is 99 (if 0 is replaced by 9) and the minimum value that can be returned by the function is 0 (if 9 is replaced by 0).</p>
<p>Thus, we return 99.</p>
<p><strong>Constraints:</strong></p>
<ul>
<li><code>1 <= num <= 10<sup>8</sup></code></li>
</ul>
