You don't. A stack is a last in first out (LIFO) structure so you only have access to the top element in the stack. If you want to locate the smallest element in the stack, you need to pop everything off the stack in order to find it, at which point the stack is completely ruined. The only way to restore a stack is to push every element onto another stack as they are popped off. The other stack will then be the reverse of the original, so you just repeat the process to transfer the elements back to the original stack.
You should really be asking why you are using a stack in the first place if the intent is to remove an element other than the top element. A forward list would be a much better option.
What else can I help you with?
How do you reverse the order of element on stack by using one additional stack and some additional non array variables?
You pop elements off of one stack and push them onto the other. This reverses the order of the elements. while ((element = pop(stack1)) != NULL) push(stack2, element);
Define list of operation on stack?
There are 4 main widely used stack operations.Operations:* POP - increase stack pointer and return top element * PUSH - putting element into stack's top * TOP - returns data of top element on stack * LENGTH/SIZE - returns number of elements inside stack For more detailed implementation details, please check web links.
What is the operation of delete in stack?
Delete is mostly commonly known as pop in stack. The last element inserted into the stack is removed from the stack. Here is an illustration:Consider the stack with the elements 1,2,3,4 inserted in order.1->2->3->4\topThe top of the stack will be pointing to 4. When pop operation is performed, 4 is removed from the stack and the top is made to point to 3. The stack then becomes:1->2->3\top
What is push operation in data structure?
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... }
How do you convert stack in queue?
To convert a stack into a queue, you can use two stacks. First, pop all elements from the original stack and push them onto the second stack. Then, to dequeue an element, simply pop from the second stack. This method allows you to maintain the queue's FIFO (first-in, first-out) property while using the LIFO (last-in, first-out) nature of stacks.
What function is used to pop and destory the stack in a single step?
Just initialize the stack pointer...stack = top;However, this will leak memory if the stored elements contain pointers, so it may be more prudent to pop each element off and delete it instead...while ((element = pop(stack)) != NULL) free (element);

What are some common operations that can be performed on a stack data structure?
Common operations that can be performed on a stack data structure include push (adding an element to the top of the stack), pop (removing the top element from the stack), peek (viewing the top element without removing it), and isEmpty (checking if the stack is empty).
What does pop mean in math form?
In mathematics, "pop" often refers to the operation of removing an element from a data structure, such as a stack or a queue. For example, in a stack, "pop" removes the top element and typically returns it, reducing the size of the stack by one. This operation is fundamental in various algorithms and data management tasks. In a more general sense, "pop" can also denote the act of extracting or discarding an item from a collection.

How can I efficiently use a stack to sort elements in a data structure?
To efficiently use a stack to sort elements in a data structure, you can follow these steps: Push all elements into the stack. Create a temporary stack to store the sorted elements. While the original stack is not empty, pop an element from the original stack. Compare the popped element with the top element of the temporary stack. If the popped element is greater, push it onto the temporary stack. If the popped element is smaller, keep popping elements from the temporary stack and pushing them back onto the original stack until the temporary stack is empty or the top element is greater. Repeat steps 3-6 until the original stack is empty. The elements in the temporary stack will now be sorted in ascending order. By following these steps, you can efficiently use a stack to sort elements in a data structure.

Where is the front of the stack in a stack-linked list?
In a stack-linked list, the front of the stack is represented by the head node of the linked list. This head node contains the topmost element of the stack, and it allows for operations like push and pop to be performed efficiently. When a new element is pushed onto the stack, it becomes the new head node, while popping removes the current head node and shifts the next node to the top of the stack.
What do you mean by stack explain the push or pop operation?
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.
When will stack overflow and stack underflow condition occur insequential organization?
In a sequential organization, a stack overflow condition occurs when there is an attempt to push an element onto a stack that is already full, exceeding its allocated memory limit. Conversely, a stack underflow condition occurs when there is an attempt to pop an element from an empty stack, which has no elements to remove. Both conditions can lead to runtime errors and need to be handled to maintain the integrity of the stack operations. Proper checks should be implemented to prevent these situations.
