Question 1 5 pts A regular expression is shorthand for a set of strings. For example (b+ba)* ba (a+ab)* represents a set of strings for which the first two elements (when listed in length order with same length strings listed in alphabetical order) are: ba and baa. What are the next three strings in this sequence? Next string: Next after that: Next after that:
Is it the same? Tags: String Problem Description Puan Ruqayyah, Madam Chong and Miss Lela teach their dyslexia students to identify characters. They tested randomly on strings of characters and numbers. They found that a few children get excited when they read certain series of strings. The teachers were curious and began to find out that these kids love strings that have series of characters that can be read similarly from right and from left.There are not that many meaningful words and numbers with such pattern. The teachers are interested to collect these meaningful words and numbers to share with their dyslexia students. Examples of such strings are CIVIC, KAPAK, 2102012 (which is 2nd Oct 2012), 1102011 (which is 1st Oct 2011), among others.Now, you are to help Puan Ruqayyah and her colleagues to select such strings. Write a program that reads in a sequence of characters and determine if it can be read similarly from right and from left. InputThe first line of input is…

Up for the count def counting_series (n): The Champernowme word 1234567891011121314151617181920212223., also known as the counting series, is an infinitely long string of digits made up of all positive integers written out in ascending order without any separators. This function should return the digit at position n of the Champernowne word. Position counting again starts from zero for us budding computer scientists. Of course, the automated tester will throw at your function values of n huge enough that those who construct the Champernowne word as an explicit string will run out of both time and space long before receiving the answer. Instead, note how the fractal structure of this infinite sequence starts with 9 single-digit numbers, followed by 90 two-digit numbers, followed by 900 three-digit numbers, and so on. This observation gifts you a pair of seven league boots that allow their wearer skip prefixes of this series in exponential leaps and bounds, instead of having to crawl…
