🔍 Solution Template

I'll be using a consistent template for each solution:

class Solution:
    def problemName(self, input_params):
        """
        Problem Description:
        - Brief explanation of the problem

        Time Complexity: O()
        Space Complexity: O()

        Args:
            input_params: Description of input

        Returns:
            Expected output type and description
        """
        # Solution implementation
        pass

# Example test cases
def test_solution():
    sol = Solution()
    # Add test scenarios

🚦How to use

# Clone the repository
git clone https://github.com/[your-username]/leetcode-75-solutions.git

# Navigate to the project directory
cd leetcode-75-solutions

# (Future) Run solutions
# python arrays_and_strings/solution.py
