+// Given a signed 32-bit integer x, return x with its digits reversed. If
+// reversing x causes the value to go outside the signed 32-bit integer range
+// [-231, 231 - 1], then return 0.
+// Assume the environment does not allow you to store 64-bit integers (signed or
+// unsigned).
+
+// Example 1:
+
+// Input: x = 123
+// Output: 321
+// Example 2:
+
+// Input: x = -123
+// Output: -321
+// Example 3:
+
+// Input: x = 120
+// Output: 21
+
+// Constraints:
+
+// -231 <= x <= 231 - 1

+        while (x != 0) {
