Input :mypqueue1 = {1, 3, 5, 7} mypqueue2 = {2, 4, 6, 8} mypqueue1.swap(mypqueue2); Output:mypqueue1 = {8, 6, 4, 2} mypqueue2 = {7, 5, 3, 1} Note:In priority_queue container, the elements are printed in reverse order because the top is printed first then moving ...

优先队列(priority queue) 普通的队列是一种先进先出的数据结构,元素在队列尾追加,而从队列头删除。在优先队列中,元素被赋予优先级。当访问元素时,具有最高优先级的元素最先删除。优先队列具有最高级先出 (first in, largest out) 的行为特征。通常采用堆数据结构来实现。

pull_highest_priority_element: remove the element from the queue that has thehighest priority, and return it. This is also known as "pop_element(Off)", "get_maximum_element" or "get_front(most)_element". Some conventions reverse the order of priorities, considering lower values to be highe...
