def fibonacci(n, memo={}):\n if n in memo:\n return memo[n]\n if n <= 1:\n return n\n memo[n] = fibonacci(n-1, memo) + fibonacci(n-2, memo)\n return memo[n]\n\nThis efficient recursive solution uses a dictionary for memoization to avoid redundant calculations, supporting the model's large context window for complex codebases.[fas fa-code]
