### 🔍 1. Root Cause Analysis The code fails because there is no base case to stop the recursion. The function keeps calling itself indefinitely with smaller numbers until Python hits its recursion limit and crashes. ### 🛠️ 2. The Optimized Fix def get_factorial(n): if n <= 1: return 1 return n * get_factorial(n - 1) result = get_factorial(5) ### 📝 3. What Changed? * Added an if statement to check if 'n' is less than or equal to 1. * Returned 1 to successfully terminate the recursive loop. ### 💡 4. Senior Developer Tip Always define your exit condition (base case) first when writing recursive functions. Without it, memory overflow is guaranteed.
