why people stress heaps used implement priority queues because time complexity of peeking @ max/min value o(1) . can't implented on bst , using pointer point @ right most/left node. given fact propose priority queue based on bst, try explain why heap better bst. a heap complete tree; balanced tree. height log_2(n+1) . a bst approach worthwhile if 1 balanced. best-known technique maintaining bst balanced avl tree. kind of tree has height bound of 1.44 log_2(n+2) - 0.33 . for consultation of minimum have cost of o(log(n)) bst versus o(1) heap. operation heap better. for insertion , deletion costs asymptotically equivalent. bst tends more expensive because height tends higher balanced tree. in addition, avl tree consumes more constant time heap. in avl (and in other balancing approaches, red-black tree, treaps, splays, etc) perform rotations, while heap perform swaps, cheaper rotations. deletion on bst complicated , expensive operation , take o(log(n)) rot...

c++ - Function pointer to member function -

i'd set function pointer member of class pointer function in same class. reasons why i'm doing complicated. in example, output "1" class { public: int f(); int (*x)(); } int a::f() { return 1; } int main() { a; a.x = a.f; printf("%d\n",a.x()) } but fails @ compiling. why? the syntax wrong. member pointer different type category ordinary pointer. member pointer have used object of class: class { public: int f(); int (a::*x)(); // <- declare saying class pointer }; int a::f() { return 1; } int main() { a; a.x = &a::f; // use :: syntax printf("%d\n",(a.*(a.x))()); // use object of class } a.x not yet on object function called on. says want use pointer stored in object a . prepending a time left operand .* operator tell compiler on object call function on.
