The problem “2235. Add Two Integers” requires you to write a function that takes two integers as input and returns their sum.

Clarifying Questions

Since the problem is straightforward, the following clarifications ensure completeness:

1. Input Range: Are there any constraints on the range of integers? (Typically, this would be the standard integer range in Python, but confirming constraints can be useful.)
2. Output Type: Should the function always return an integer?
3. Handling Exceptions: Should we handle cases where the inputs aren’t integers, or can we assume they will always be integers?

Code

Below is a simple implementation of the function to add two integers:

def sum_two_integers(a: int, b: int) -> int:
    return a + b

# Example Usage
result = sum_two_integers(5, 3) 
print(result)  # Output: 8

Strategy

1. Input Verification: Assuming the inputs are always integers allows skipping explicit type checks.
2. Summation: Use the + operator to sum the two integers and return the result.
3. Testing: Include some example cases for verification.

Time Complexity

The time complexity of this function is O(1):

• Constant Time Operation: Adding two integers is a basic arithmetic operation that takes constant time.

This simplicity ensures efficiency and effectiveness for the given problem.
