How do you sort a stack with another stack?

How do you sort a stack with another stack?

Sort a stack using a temporary stack

  1. Create a temporary stack say tmpStack.
  2. While input stack is NOT empty do this: Pop an element from input stack call it temp. while temporary stack is NOT empty and top of temporary stack is greater than temp,
  3. The sorted numbers are in tmpStack.

Is it possible to sort a stack?

Given a stack, sort it using recursion. Use of any loop constructs like while, for..etc is not allowed. The idea of the solution is to hold all values in Function Call Stack until the stack becomes empty. …

What is the time complexity to sort elements of a stack?

If the initial collection is reverse-sorted, this will happen with each insertion, making the complexity O(N2). Inserting n elements without sorting would be o(n). As each sort is o(n), the total is O(n^2). Worst case: numbers are presented in the reversed order.

How do you initialize a stack?

Initialize Stack in C++ STL

  1. T is the datatype of elements in the stack like int, float.
  2. container is the data structure used to initialize your stack. This is optionally and by default, it will be deque and can be set to other values like vector .
  3. container_instance is the instance of container type.

What is the minimum number of stack required to reverse the content of stack?

How many stacks are required for reversing a word algorithm? Explanation: Only 1 stack is required for reversing a word using stack. In that stack, push and pop operations are carried out.

How do I move elements from one stack to another?

We follow the below steps to reverse the source stack:

  1. Initialize a variable count to 0.
  2. Pop the top element from the source stack and store it in variable topVal.
  3. Now pop the elements from the source stack and push them into the dest stack until the length of the source stack is equal to count.

How to sort a stack using recursion algorithm?

We can use below algorithm to sort stack elements: sortStack(stack S) if stack is not empty: temp = pop(S); sortStack(S); sortedInsert(S, temp); Below algorithm is to insert element is sorted order:

How to use ADT to sort a stack?

We can only use the following ADT functions on Stack S: is_empty (S) : Tests whether stack is empty or not. push (S) : Adds new element to the stack. pop (S) : Removes top element from the stack. top (S) : Returns value of the top element. Note that this function does not remove element from the stack.

How to sort stack using a temporary stack?

We follow this algorithm. Create a temporary stack say tmpStack. Here is a dry run of above pseudo code. This article is contributed by Aditya Nihal Kumar Singh.

Can you write a C program to sort the stack?

I found this question on the web. Given a stack S, write a C program to sort the stack (in the ascending order). We are not allowed to make any assumptions about how the stack is implemented. The only functions to be used are:
