Check if stack elements are pairwise consecutive | Function to check if elements are pairwise consecutive in stack.
Transfer elements of s to aux ..
Traverse aux and see if elements are pairwise consecutive or not . We also need to make sure that original content is retained ..
Fetch current top two elements of aux and check if they are consecutive ..
append the elements to original stack ..
Driver Code"
How can the above be solved in Python?
 Give me a code to check if stack elements are pairwise consecutive and the other steps required?
