Brute force is a direct problem-solving strategy where all possible solutions are explored until the correct one is found.It doesn’t rely on advanced heuristics and optimizations and so helps in understanding and solving problems.Here are some common brute force problems with Python code, detailed time and space complexity analysis, and optimized patterns:1. String Matching - Time Complexity: O(n * m) and Space Complexity: O(1)2. Finding Duplicates - Time Complexity: O(n²) and Space Complexity: O(1)3. Maximum Subarray Sum - Time Complexity: O(n³) and Space Complexity: O(1)4. Palindrome Check - Time Complexity: O(n³) and Space Complexity: O(1)5. Two Sum Problem - Time Complexity: O(n²) and Space Complexity: O(1)6. Fibonacci Sequence - Time Complexity: O(2ⁿ) and Space Complexity: O(n)By identifying patterns like Dynamic Programming, Hashing, and Matrix Exponentiation, performance and scalability can be improved.
