$2.$ Iterators: Write a function that takes two equal$-$length lists as input and returns an iterator.

The iterator should yield elements from the two lists alternately without creating a new list

to store the combined elements. Implement the solution using iterators, such as a for loop

or the next $()$ method."

pg$.2$

For example:

input:

list$1=[1,2,3,4,]$

list$2=[$a$,$b$,$c$,$d$]$

output:

$1$a$2$b$3$c$4$d

Hint: An iterator is an object that implements $\_\_$iter$\_\_,$ which is expected to return

an iterator object. An iterator object implements $\_\_$next$\_\_,$ which is expected to return the

next element of the iterable object that returned it$.$

Implement a function that takes two lists of equal length as input. The objective is to solve

the problem using iterators, such as a for loop or the next$()$ method, instead of creating a

new list to store the combined elements of the two lists. The function should return an

iterator that yields the elements from the two lists alternately. It should iterate through the

lists and yield one element from the first list, then one element from the second list, and so

on$,$ until all elements have been exhausted.
