Let S be a stack with the following elements, 6,13,15,17,35,45,20,55. Implement the stack using an Array and Linked-list
Recursion and list processing
Write a maxel that returns the maximum element in an arbitrarily complex list (e.g., list that may contain lists, which may contain lists, and so on). For example,

- The N Queen is the problem of placing N chess queens on an N×N chessboard so that no two queens attack each other. Two queens are said to attack each other if they are placed on the same row, same column or if they are diagonally placed. Given the value of ‘n’ as input, write a recursive in C++ procedure with an external stack to find all solutions to place them on a n x n board such that they do not attack each other.arrow_forwardSolve it and if u need to use code do it by java language 5.

None of the precedingarrow_forwardFind out how the stack performs when let to be who it is.arrow_forwardSolve the code much needed. Given a stack, a function is_consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] topThe function should return false due to reverse order. Note: There are 2 solutions:first_is_consecutive: it uses a single stack as auxiliary storagesecond_is_consecutive: it uses a single queue as auxiliary storage"""import collections def first_is_consecutive(stack): storage_stack = [] for i in range(len(stack)): first_value = stack.pop() if len(stack) == 0: # Case odd number of values in stack return True second_value = stack.pop() if first_value - second_value != 1: # Not…arrow_forward
