add-two-integers/solution.pyThis is the solution to LeetCode problem #2235 "Add Two Integers." It's about as minimal as a LeetCode problem gets — return the sum of two ints. Its real significance in this repo is structural: it follows the same Solution class convention as every other problem directory, making it a canonical example of the project's solution template.
Solution.sum(self, num1: int, num2: int) -> int — The only method. Takes two integers in the range [-100, 100] and returns their sum. The docstring documents the constraint range from the problem statement, but no runtime validation enforces it.
Solution class convention: Every problem in this repo wraps its answer in a class Solution with a method matching the LeetCode function signature. This lets the test harness instantiate Solution() and call the method uniformly.-100 <= num1 <= 100) rather than implementation details — a pattern repeated across the repo to keep the original problem context alongside the code.Imports: None. This file is self-contained with no standard library or third-party imports.
Imported by: The "Imported By" list in the prompt is misleading — those are test files from *other* problem directories, not actual importers of this module. The real consumer is add-two-integers/testsolution.py, which imports this Solution class to run test cases against it. The massive import list likely reflects a shared test infrastructure pattern where testsolution.py files across the repo follow an identical import-and-test template.
1. Caller instantiates Solution().
2. Caller invokes solution.sum(num1, num2).
3. Python evaluates num1 + num2 and returns the result.
There is no branching, no iteration, no state.
[-100, 100] per the problem spec, but does not validate this at runtime. This is standard for LeetCode solutions where the judge guarantees valid input.None. No validation, no try/except, no sentinel values. If called with non-integer types, Python's built-in + operator will either work (floats) or raise a TypeError — but that's outside the problem contract.
