Simple dictionary
Input
iterate_dict({'a': 1, 'b': 2})
Output
[('a', 1), ('b', 2)]
The items are returned as a list of tuples in insertion order.

Problem statement
Given a dictionary, return a list containing (key, value) tuples for each entry in the dictionary. The order should reflect the dictionary's insertion order. The function should not print anything; it should return the list so that it can be tested.
Task
Implement a function that returns the dictionary's items as a list of (key, value) tuples in insertion order.
Examples
Input format
A single dictionary passed to iterate_dict(d).
Output format
A list of tuples [(key1, value1), (key2, value2), ...].
Constraints
Dictionary may be empty. Keys and values can be any types that can be stored in a dict.
Samples
Sample 1
Input
iterate_dict({1: 2, 3: 4})
Output
[(1, 2), (3, 4)]
Numbers are returned as (key, value) tuples in the same order they were written.
