Push inserts a value onto the top of the stack.
Pop extracts the top value from the stack.
These are the two primary operations that can be performed upon a stack. Prior to popping a value, you will first check the stack is not empty, store the top value, then pop the stack. For a stack of type T, you might use the following:
if (!stack.empty()) {
T value {stack.top()}; // copy top value
stack.pop(); // remove value from stack
// use value...
}

A stack is a linear data structure that follows the Last In, First Out (LIFO) principle, meaning the last element added is the first one to be removed. The "push" operation adds an element to the top of the stack, while the "pop" operation removes the element from the top. Both operations are typically performed in constant time, O(1), making stacks efficient for various applications, such as function call management and expression evaluation in programming.
One alternative approach to implementing the Dijkstra algorithm without using the decrease key operation is to use a data structure called a bucket queue. This data structure allows for efficient updates of node priorities without the need for the decrease key operation.
To efficiently implement the decrease-key operation in a priority queue, you can use a data structure like a binary heap or Fibonacci heap. These data structures allow for efficient updates to the priority queue while maintaining the heap property, which helps optimize performance.
Push and pop are properties of a stack (also called a LIFO-- Last In, First Out-- queue).

The priority queue decrease key operation can be efficiently implemented by using a data structure like a binary heap or a Fibonacci heap. These data structures allow for the key of a specific element in the priority queue to be decreased in logarithmic time complexity, making the operation efficient.

Circular queue is a linear data structure that follows the First In First Out principle. A re-buffering problem often occurs for each dequeue operation in a standard queue data structure. This is solved by using a circular queue which joins the front and rear ends of a queue.
