TL;DR: Array-based queues are often dismissed due to O(n) shifting costs, but the ring buffer circumvents this by using wrapping head and tail pointers. This design provides O(1) access and superior cache locality, making it the industry standard for CPU scheduling, video buffering, and high-performance data streaming. I’ve seen plenty of developers dismiss array-based queues as a rookie mistake, but the hardware you're using right now relies on them. On paper, it looks inefficient to use a fixed-size array for a queue because removing an element from the front forces an O(n) operation to move
