Problem statement
Given a list, iterate over it in reverse order and return a new list containing the elements from last to first. Do not simply call list.reverse() in-place; produce a new list by iterating in reverse.
Task
Practice iterating in reverse using loops and return the reversed sequence as a new list.
Examples
Input format
A single list: iterate_in_reverse(lst)
Output format
A list with elements in reverse order: [last, ..., first]
Constraints
- The input list may be empty.
- Preserve elements as-is (do not copy or transform them beyond reordering).
Samples
Sample 1
Input
iterate_in_reverse(['a','b'])
Output
['b', 'a']
Reversed order of two elements.
