2119 - A Number After a Double Reversal\. Easy **Reversing** an integer means to reverse all its digits. * For example, reversing `2021` gives `1202`. Reversing `12300` gives `321` as the **leading zeros are not retained**. Given an integer `num`, **reverse** `num` to get `reversed1`, **then reverse** `reversed1` to get `reversed2`. Return `true` _if_ `reversed2` _equals_ `num`. Otherwise return `false`. **Example 1:** **Input:** num = 526 **Output:** true **Explanation:** Reverse num to get 625, then reverse 625 to get 526, which equals num. **Example 2:** **Input:** num = 1800 **Output:** false **Explanation:** Reverse num to get 81, then reverse 81 to get 18, which does not equal num. **Example 3:** **Input:** num = 0 **Output:** true **Explanation:** Reverse num to get 0, then reverse 0 to get 0, which equals num. **Constraints:** * 0 <= num <= 106
