Beginner Issue #2 Solution

Problem #2

Complete the look_up_profile() function that takes name and a field as arguments included below
The function should check if name is an actual contact's firstName and the given field exists in that contact dictionary.
If both are true, then return the "value" of that field.
If name does not correspond to any contacts then return "No such contact"
If the field does not correspond to any valid properties of a contact found to match name then return "No such property"

Solution

Iterate the dictionary and lookup if the attributes are present. Runs at O(N) time.
