2 * [2710] Remove Trailing Zeros From a String
3 *
4 * Given a positive integer num represented as a string, return the integer num without trailing zeros as a string.
5 *  
6 * <strong class="example">Example 1:
7 * 
8 * Input: num = "51230100"
9 * Output: "512301"
10 * Explanation: Integer "51230100" has 2 trailing zeros, we remove them and return integer "512301".
