The idea behind this is mainly educational but I might even consider using it in reality if turns out to be good. Here's my first try at implementing smart pointers: template<typename T> class smart_pointer{ T* pointer; std::size_t *refs; void clear(){ if (!--*refs){ delete point...
Time Complexity of Stack Operations Only a single element can be accessed at a time in stacks. While performingpush()andpop()operations on the stack, it takesO(1)time. Conclusion In this article, you learned the concept of stack data structure and its implementation using arrays in C. Conti...
The most common stack implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Stack implementation in python # Creating a stack def create_stack(): stack = [] return stack # Creating an empty stack def check_empty(stack): return len(stack) == 0...
objects into and remove from stack a pointer usually calledtopis maintained that points to last inserted item. However, in linked implementation of stack we don't exactly require thetoppointer because we will add an item at the beginning of the list and remove it from the beginning of the ...
(or moved forward), and when an element is popped off the stack, the stack pointer is decremented (or moved back). how does the pop operation work in a stack? the pop operation removes the top element from the stack and returns it. if the stack is implemented as an array, this ...
Sample implementation I wrote my own radix sort program to see how it would fare versus the original program. It's rather long and written in C: /// This program does an inplace sort of a file using radixsort combined with// quicksort. There is a limitation on the amount of ...
While the implementation of the prologue may differ depending on a compiler that was used, generally this is done by using PUSH/ADD/SUB instructions. An example of a prologue would look like this: push {r11, lr} /* Start of the prologue. Saving Frame Pointer and LR onto the stack */ ...
typically, you can only view the top element of a stack, which is the last item that was added. however, depending on the implementation and the language, there may be ways to view all the elements in the stack using debugging tools or by converting the stack to another data structure. ...
