Shift-to-Middle Array: A Faster Alternative to Std:Deque?

Shift-To-Middle Array The Shift-To-Middle Array is a dynamic array designed to optimize insertions and deletions at both ends, offering a high-performance alternative to std::deque , std::vector , and linked lists. It achieves this while maintaining contiguous memory storage, improving cache locality and enabling efficient parallel processing. 🌟 Features ✅ Amortized O(1) insertions & deletions at both ends ✅ Fast random access (O(1)) ✅ Better cache locality than linked lists ✅ Supports SIMD & parallel optimizations ✅ Efficient memory usage compared to std::deque 📌 How It Works Unlike std::deque , which uses a fragmented block structure, the Shift-To-Middle Array dynamically redistributes space to avoid costly shifts. When resizing, elements are moved toward the middle, ensuring efficient insertions at both ends without excessive copying. 🚀 Time Complexity Comparison The following table compares the time complexity of Shift-To-Middle Array operations with other common data st ...
