+ * 2119. A Number After a Double Reversal
+ * https://leetcode.com/problems/a-number-after-a-double-reversal/
+ * Difficulty: 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.

+ * @param {number} num
+ * @return {boolean}

+var isSameAfterReversals = function(num) {
