+LeetCode Problem: Remove Zeros from a Number
+--------------------------------------------
+Description:
+Given a number n, remove all the zeros from it and return the resulting number.
+
+Example:
+Input: n = 102030
+Output: 123
+
+Approach:
+Convert the number to a string, remove all '0' characters using String.replace(),
+and parse the result back to a long.
+
+Time Complexity: O(d), where d is the number of digits.
+Space Complexity: O(d)
