Questions & Step-by-Step Solutions
In a priority queue, how is the priority of elements typically determined?
Step 1: Understand what a priority queue is. It is a data structure where each element has a priority assigned to it.
Step 2: Know that elements with higher priority are processed before those with lower priority.
Step 3: Realize that the priority can be determined by a custom comparator function. This function compares two elements to decide which one has higher priority.
Step 4: The comparator function can be based on different criteria, such as numerical value, alphabetical order, or any other custom rule.
Step 5: When adding elements to the priority queue, the comparator function is used to assign their priorities.
