Single File Programming QuestionProblem StatementGiven an integer K and a queue of integers, reverse the order of the first K elements of the queue, leaving the other elements in the same relative order. Note: You can use either an array or a linked list for implementation.Input format :The first line of input consists of an integer N, representing the number of elements in the queue.The second line consists of the value of K.The third line consists of N space-separated queue elements.Output format :The output displays "Reversed queue: " followed by the queue elements after the reversal is done, separated by a space.Refer to the sample output for formatting specifications.Code constraints :N > 0K ≤ NSample test cases :

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
