![]() And as Walter, Fassbender displays a more restrained, machine-like personality but still conveying a sense of loyalty to the crew. David gets to be a lot more fleshed out and we get a better understanding behind his questionable actions. But this time he shows off double the effort when he plays two androids, the original David and the Covenant's own personal android Walter. Once again Michael Fassbender proves to be the standout of this film. While it does not explain everything that was left open in Prometheus, it does feel satisfying that Covenant tries to give some answers rather then just leave with questions. From the opening scene of android David's "birth" to the crew of the Covenant being a colony ship carrying couples, the film carries on these philosophical ideas while tying in very well with the origin of the iconic Xenomorph. The film constantly delves on the ideas of creation, religion and faith without feeling as forced like in Prometheus. The parts I liked the most surprisingly were the Prometheus tie-ins. Covenant improves on those ideas with better-written characters but in the end mostly fails as a memorable Alien film. However, I could see that it was poorly executed especially when connecting to Alien. I was one of the people who didn't hate Prometheus because I admired the new mythology Ridley Scott was trying to create.

The idea is to create a graph of characters and then find topological sorting of the created graph. Following are the detailed steps.ġ) Create a graph g with number of vertices equal to the size of alphabet in the given alien language. For example, if the alphabet size is 5, then there can be 5 characters in words. Initially there are no edges in graph.Ģ) Do following for every pair of adjacent words in given sorted array. ….a) Let the current pair of words be word1 and word2. One by one compare characters of both words and find the first mismatching characters. ….b) Create an edge in g from mismatching character of word1 to that of word2.ģ) Print topological sorting of the above created graph. The implementation of the above is in C++. Time Complexity: The first step to create a graph takes O(n + alpha) time where n is number of given words and alpha is number of characters in given alphabet. The second step is also topological sorting. Note that there would be alpha vertices and at-most (n-1) edges in the graph. The time complexity of topological sorting is O(V+E) which is O(n + alpha) here. So overall time complexity is O(n + alpha) + O(n + alpha) which is O(n + alpha).Įxercise: The above code doesn’t work when the input is not valid. #Out there omega edition alien language code ![]() (1) Compare 2 adjacent words at a time (i.e, word1 with word2, word2 with word3, …, word(startIndex) and word(startIndex + 1) Extend the above program to handle invalid inputs and generate the output as “Not valid”.Īpproach 2: For example is not valid, because from first two words, we can deduce ‘a’ should appear before ‘b’, but from last two words, we can deduce ‘b’ should appear before ‘a’ which is not possible. (2) Then we compare one character at a time for the 2 words selected. (2a) If both characters are different, we stop the comparison here and conclude that the character from word(startIndex) comes before the other. (2b) If both characters are the same, we continue to compare until (2a) occurs or if either of the words has been exhausted. (3) We continue to compare each word in this fashion until we have compared all words. Once we find a character set in (2a) we pass them to class ‘AlienCharacters’ which takes care of the overall ordering of the characters. The idea is to maintain the ordering of the characters in a linked list (DNode). To optimize the insertion time into the linked list, a map (C# Dictionary) is used as an indexing entity, thus, bringing down the complexity to O(1). This is an improvement from the previous algorithm where topological sort was used for the purpose.Ģ. #Out there omega edition alien language code.
