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 &ldquo;Danny Mittal&rdquo; 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>
