Problem Description

Given two integers, num1 and num2, return the sum of the two integers.

Key Insights

  • The problem is a simple arithmetic addition.
  • No edge cases beyond handling negative numbers and zeros.
  • Constraints are small, so performance and overflow are not concerns.
  • A direct addition operation (num1 + num2) produces the answer.

Space and Time Complexity

Time Complexity: O(1) - the solution performs a single addition. Space Complexity: O(1) - no additional space is required.

Solution

The solution involves taking the two integer inputs and performing a direct addition. Since all operations are basic arithmetic, no additional data structures or complex algorithms are needed. The key insight is that the addition operator is sufficient to solve the problem, with constant time and constant space complexity.

Code Solutions

# Function to add two integers
def addTwoIntegers(num1, num2):
    # Return the sum of the two numbers
    return num1 + num2

# Example usage:
print(addTwoIntegers(12, 5))  # Expected output: 17
