C++ stack queue collections STL
stack
Write a function named issorted accepts a reference to a stack of integers as a parameter and returns
true if the elements in the stack occur in ascending (non-decreasing) order from top to bottom, else false.
That is, the smallest element should be on top, growing larger toward the bottom. An empty or one-element
stack is considered to be sorted. For example, if passed the following stack, your function should return
true:
bottom {20, 20, 17, 11, 8, 8, 3, 2) top
The following stack is not sorted (the 15 is out of place), so passing it to your function should return a result
of false:
bottom {18, 12, 15, 6, 1} top
When your function returns, the stack should be in the same state as when it was passed in. In other words,
if your function modifies the stack, you must restore it before returning.
Constraints: You may use one queue or one stack (but not both) as auxiliary storage. Do not declare any
other auxiliary data structures (e.g. arrays, Grids, vectors, etc.), but you can have as many simple variables as
you like. Your solution should run in O(N) time, where N is the number of elements of the stack.
