Define a Function to iterate over a dictionary

Define a function that takes a dictionary as a parameter and iterates over its key:value pairs. The Function should return a sorted list containing tuples of the key-value pairs.

Example:

Input:

{1: 10, 2: 20, 3: 30, 4: 40}

Output:

[(1, 10), (2, 20), (3, 30), (4, 40)]
