:::spoiler Note (筆記)
Extract from: [Leetcode solution](https://leetcode.com/problems/add-two-integers/solutions/4903679/best-solution-in-python-with-explanation/)
**Explanation**

The Solution [class](https://ithelp.ithome.com.tw/articles/10284380) (類別) is defined, which contains a **method** (函式) named ==sum==.

The sum method takes two **parameters** (變數) ==num1== and ==num2==, both of which are integers.

Inside the method, the sum of ==num1== and ==num2== is calculated using the ==+== operator.

The method ==returns== the result of the addition operation, which represents (代表) the sum of the two integers.

The time and space complexities of this solution are both **O(1)**, as the addition operation and memory usage (運用) do not depend on the size of the input integers.
