decrease-key operation
A "decrease-key operation" is a procedure that is used to decrease the priority or value associated with a specific element in a data structure, such as a priority queue or a heap. This operation allows for modifying the position of an element in the data structure based on its new priority or value, while maintaining the overall integrity and order of the data structure. It is commonly used in algorithms and data structures that require efficient updates to prioritize or process elements based on their priorities or values.
