Combine Two Dictionaries Write a program to combine two dictionaries updating values for common keys. Input The first line of input will contain space-separated strings, denoting the keys of first dictionary. The second line of input will contain space-separated integers, denoting the values of first dictionary. The third line of input will contain space-separated strings, denoting the keys of second dictionary. The fourth line of input will contain space-separated integers, denoting the values of second dictionary. Output The output should be a single line containing the list of tuples of dictionary items with all the key-value pairs of two dictionaries sorted in ascending order by key.
