All the numbers less than or equal to the current median are.. can be in either heap. The count of numbers in the two heaps never differs by more than 1. When the process begins the two.. differs by more than 1. When the process begins the two heaps are initially empty. The first number in the input sequence..

Easiest way of using min priority queue with key update in C++ http://stackoverflow.com/questions/9209323/easiest-way-of-using-min-priority-queue-with-key-update-in-c works most textbooks usually recommend using binary heaps to implement priority queues as the time of building the binary.. priority queues as the time of building the binary heaps is just O N . I heard that there is a built in priority queue.. priority queue data structure in STL of C that uses binary heaps. However I'm not sure how to update the key_value for that data..
