2520 - Count the Digits That Divide a Number.<p>Easy</p> <p>Given an integer <code>num</code>, return <em>the number of digits in <code>num</code> that divide</em> <code>num</code>.</p> <p>An integer <code>val</code> divides <code>nums</code> if <code>nums % val == 0</code>.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> num = 7</p> <p><strong>Output:</strong> 1</p> <p><strong>Explanation:</strong> 7 divides itself, hence the answer is 1.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> num = 121</p> <p><strong>Output:</strong> 2</p> <p><strong>Explanation:</strong> 121 is divisible by 1, but not 2. Since 1 occurs twice as a digit, we return 2.</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> num = 1248</p> <p><strong>Output:</strong> 4</p> <p><strong>Explanation:</strong> 1248 is divisible by all of its digits, hence the answer is 4.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= num <= 10⁹</code></li> <li><code>num</code> does not contain <code>0</code> as one of its digits.</li> </ul>
