👉 In the context of data structures and algorithms, a "core sign" or "core signature" is a set of rules that define a particular algorithm's behavior. It involves specifying the structure and operations of an algorithm in order to ensure that it behaves as intended.
For instance, consider a sorting algorithm like QuickSort. The core sign specifies the following:
1.
Sorting Order
: Sorts elements based on the key function `key` provided.
2.
Key Function
: Takes an element as
