1903 - Largest Odd Number in String\. Easy You are given a string `num`, representing a large integer. Return _the **largest-valued odd** integer (as a string) that is a **non-empty substring** of_ `num`_, or an empty string_ `""` _if no odd integer exists_. A **substring** is a contiguous sequence of characters within a string. **Example 1:** **Input:** num = "52" **Output:** "5" **Explanation:** The only non-empty substrings are "5", "2", and "52". "5" is the only odd number. **Example 2:** **Input:** num = "4206" **Output:** "" **Explanation:** There are no odd numbers in "4206". **Example 3:** **Input:** num = "35427" **Output:** "35427" **Explanation:** "35427" is already an odd number. **Constraints:** * 1 <= num.length <= 105 * `num` only consists of digits and does not contain any leading zeros.
