Returns a new deque object initialized left-to-right (using append()) with data from iterable. Common Mistake #3: Specifying parameters incorrectly for an exception block. But i also did the same thing but instead of using pop fuction i use list_name. A word chain is a sequence of words [word_1, word_2, , word_k] with k >= 1, where word_1 is a predecessor of word_2, word_2 is a predecessor of word_3, and so on. Second off, given that this is from Hackerrank, there are thousands of solutions, so if your code is "clean" and the problem is easy enough (only a list data structure, and one iteration is necessary for this particular problem), it's without a doubt that there will be a solution Hackerrank has received (in this case from over a year ago) that. Summary of Styles and Designs. The array is passed to the function, and a new array is created, and contents of the passed array (in reverse order) are copied into it, and finally, contents of the new array are copied into the array passed to the function.
