Given any number of arrays containing numbers, write a function which finds the numbers that appear in exactly two arrays. arrays = [ [6, 2, 2, 0, 4], [5, 0, 2, 6, 7, 1], [6, 7, 9, 9], ] find_in_two(arrays) should return [2, 0, 7]
input log = [ { 'user': 'A', 'page': 1}, { 'user': 'B', 'page': 5}, { 'user': 'A', 'page': 2}, { 'user': 'A', 'page': 1}, { 'user': 'B', 'page': 2}, { 'user': 'C', 'page': 7}, { 'user': 'C', 'page': 3}, { 'user': 'A', 'page': 3}, { 'user': 'C', 'page': 1}, ] please implement discover_site_map(log) discover_site_map returns a representation of the links between pages, using whatever data structure you think is suitable: 1 -> 2, 3 2 -> 1 3 -> 1 5 -> 2 7 -> 3
