Much like the regular look-and-say sequence, we are able to study this sequence by constructing a “basis” of non-interacting subsequences that every term in the binary look-and-say sequence is made up of. Is it natural to use "difficult" about a person? To generate a member of the sequence from the previous member, read off the digits of the previous member, counting the number of digits in groups of the same digit. Objectives. Loss of taste and smell during a SARS-CoV-2 infection. )\k* but it'll make the regex one char longer, so I've used \\$_ which evaluates to \1. This sequence is also known as the Morris Number Sequence. Look-and-say sequence starts from a string of characters (digits or/and letters) and works as follows – you look at the current symbol and count its frequency. Look-and-say sequence examples written in Java (by Kevin) / Please visit http://goo.gl/X94gN for more details. I also alias partial and comp to one-letter names (hurrah for first class functions!). Prints Look-and-say sequence. Suppose we have a number n we have to generate nth term in “Look and Say” sequence. Seems to be a common omission in statically typed languages though for some reason. For example, if you look at "22a", you count "two twos" and "one a" so the next sequence element is "221a", and then you repeat this process. I then use math to find the number 20, so I can use it for taking this number of elements from an infinite sequence of look-and-say strings: 2^4 + 4 = 20. I thought it would be a very straight forward iterative approach and I could solve it in few minutes. The look-and-say sequence is also known as the Morris Number Sequence, after cryptographer Robert Morris, and the puzzle What is the next number in the sequence … Today, we continue that journey through the eyes of a Scala enthusiast. @mellamokb: Fixed at a cost of 18 characters. Also, the k4 solution you included is a slight improvement, but on Kona/K2 it requires tweaks-, Episode 306: Gaming PCs to heat your home, oceans to cool your data centers. 5 and get: 1 11 21 1211 111221 I let this be o (one), and then let t (two) be (+ o o), and let f (four) be (+ t t). I will accept the answer which works and is the shortest; in case of a tie, vote counts will decide, and in case of a tie there, the winner will be chosen randomly. In each subsequent entry, the number of appearances of each integer in the previous entry is concatenated to the front of that integer. 1 (One) 11 (One 1) So read the previous 1, and say “One 1” 21 (Two 1) So read the previous 11, and say … Story of a student who solves an open problem. (method A - initial term is 1). 1. Then T test cases follow . @Thomas: My inclination here is to close this as based on too subjective a criterion. Language of the month for January 2021: Scala, Quickly find length of n-th term of the look-and-say sequence. Java Solution. Underbrace under square root sign plain TeX, Missing I (1st) chord in the progression: an example, unix command to print the numbers after "=". Look and Say Sequence The look and say sequence reads a single integer. He coded it (for free) in less than zero seconds, while sleeping. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Over the last week we’ve been taking a journey through ways to think differently about how to code the Look-and-Say sequence using some code examples. For example: 1 is read off as "one 1" or 11. By "number" do you mean "character 0-9" or "numeric literal"? Best of CGCC 2020 - Now Accepting Nominations! Partition and composition calculator work in progress by Henry Bottomley 2002/2003. Show activity on this post. Here is my code in Ruby that shows the look-and-say sequence.
