Priority queueis an abstractdatatype which is used to insert or remove an element according to priority. It works as assigning a priority to the process or thread to execute accordingly. There are two ways to implement priority queue dynamically: using linked list and using heap. Inserting an ...
IS_EMPTY(STACK,TOP,MAX,STATUS) Algorithm to check stack is empty or not. STATUS contains the result status. 1) IF TOP = 0 then STATUS:=true; 2) Otherwise STATUS:=false; 3) End of IF 4) Exit Complete program to implement stack using above functions & algorithms...

generic type parameter and array resizing (both growing and shrinking), but it doesn't have to support iterators.Hints:Queue is a FIFO data structure ; the API for a queue contains enqueue, dequeue,size and isEmpty methods in addition to the constructor; you don't have to implement ...
It has a different space utilization, but if you implement it just like BFS, but using a stack rather than a queue, you will use more space than non-recursive DFS. Why more space? Consider this: // From non-recursive "DFS" for (auto i&: adjacent) { if (!visited(i...
