Pull request overview
This pull request adds comprehensive solutions to three LeetCode problems from the 116th weekly contest: problems 0962 (Maximum Width Ramp), 0963 (Minimum Area Rectangle II), and 0964 (Least Operators to Express Number).
- Implements monotonic stack solution for finding maximum width ramps in O(n) time complexity
- Adds geometric algorithm for finding minimum area rectangles with arbitrary rotation angles
- Provides dynamic programming with memoization approach for minimizing operators to express numbers

| File | Description |
|---|---|
| solution/0900-0999/0962.Maximum Width Ramp/ | Added monotonic stack solution in Python, Java, C++, Go, TypeScript, and JavaScript with complete problem documentation in both Chinese and English |
| solution/0900-0999/0963.Minimum Area Rectangle II/ | Implemented O(n³) solution for finding minimum area rectangle with support for rotated rectangles, including hash-based point lookup optimization |
| solution/0900-0999/0964.Least Operators to Express Number/ | Added recursive DFS solution with memoization to minimize operators needed to express target numbers |
Note: I identified a potential bug in the C++ implementation of problem 0962 where the loop condition for (int i = n - 1; i; --i) terminates at i=1 instead of i=0, which differs from all other language implementations (Python, Java, Go, TypeScript, JavaScript) that iterate through index 0. However, I was unable to store this as a comment because the actual diff/changes are not available in the review context.
