Solution

Here is a step-by-step solution to the problem:

  1. First, we need to create an array to represent the queue. In Python, we can use a list for this. We can initialize the queue with the given elements.

  2. Next, we need to reverse the first K elements of the queue. We can do this by slicing the first K elements from the queue, reversing them, and then concatenating them with the rest of the queue.

  3. Finally, we print the reversed queue.

Here is a Python code snippet that implements these steps:

def reverse_queue(n, k, queue):
    # Reverse the first K elements
    queue[:k] = queue[:k][::-1]
    return queue

# Test the function
n = 5
k = 4
queue = [1, 2, 3, 4, 5]
print("Reversed queue: ", end="")
print(*reverse_queue(n, k, queue))

In this code, n is the number of elements in the queue, k is the number of elements to reverse, and queue is the queue of integers. The * operator in the print statement is used to print the elements of the list separated by spaces.

Reversing the first K elements of a Queue

Given a stack of `N` elements(integers), interleave the first half of the stack with the second half reversed using only one other queue. This should be done in-place.Recall that you can only push or pop from a stack, and enqueue or dequeue from a queue.For example,if the stack is `[1, 2, 3, 4, 5]`, it should become `[1, 5, 2, 4, 3]`.If the stack is `[1, 2, 3, 4]`, it should become `[1, 4, 2, 3]`.Hint: Try working backwards from the end state.Instruction: To test your code and to run your custom test cases, provide input as mentioned in the visible sample test cases.Sample Test CasesTest Case 1:Expected Output:Enter·the·elements·of·the·stack·separated·by·space:·1 2 3 4 5Stack:·[1,·2,·3,·4,·5]Stack·after·interleaving·the·first·half·with·the·reversed·second·half:[1,·5,·2,·4,·3]

Reversal ChallengeImagine you are working as an employee in an MNC, where your manager knows that you are very good at coding in arrays. He has provided you a vigorous training on data structures, so he challenges you to do the reversal of an elements using linked lists.Constraints:Input Format :The input contains a set of integers.Output Format :The output contains reversed set of given integers.Example:Input 1:51  2  3  4  5Output 1:5  4  3  2  1Input 2:411  12  14  13Output 2:13  14  12  11Explanation:Reverse the elements sequence in the given linked listPublic Test Cases:# INPUT EXPECTED OUTPUT1 5 1 2 3 4 5 5 4 3 2 12 4 11 12 14 1313 14 12 11

Consider the queues Q1 containing four elements and Q2 containing none (shown as the Initial State in the figure). The only operations allowed on these two queues are Enqueue (Q, element) and Dequeue (Q). The minimum number of Enqueue operations on Q1 required to place the elements of Q1 in Q2 in reverse order (shown as the Final State in the figure) without using any additional storage is ______________.*2 points4568
