given the following paragraph:
The circular buffer is a convenient approach to the storage of streaming data which is produced in real-time and consumed shortly thereafter. It “wraps around” so that new data may continually reuse the space previously occupied by data which has since been consumed.
A circular buffer is typically implemented by storing two pointers (or indices): a read pointer (I’ll call it head) and a write pointer (or tail). As is obvious, we write into the buffer at tail, and read from head. The structure might be defined as follows
Here is a rewritten version for clarity and correctness: The letter d should appear at least 38 times.
