Question 1
Please complete this question on your preferred IDE and send me back a link with your code and answer. # In this problem, you are given a set of house listings and your job is to return a list of the most recent listing of each address. # There could be multiple listings of the same address, and you must ensure your ouput contains only one listing per address (the most # recent one). A listing contains a name, address, and date. # For example: # Input: # L4, 123 kings road,2022 # L1, 123 kings road,2020 # L2, 20 queen road,1990 # L3, 20 queen road,1992 # Expected Output: # (L4, L3) # In the above example, there are two listings with the same address "123 kings road", and two listing with the same address "20 queen road". # The output includes the most recent listing with the address "123 kings road" (2022 > 2020) which is L4, and the most recent listing with # the address "20 queen road" (1992 > 1990) which is L3, hence (L4, L3).
