Actual type is `Maybe (Maybe [(Nucleotide, Int)])` when I expect it to be `[(Nucleotide, Int)]`

Asked 2021-Feb-28 at 03:12

I'm currently learning Haskell and am working on the Nucleotide Count problem on https://exercism.io/. The problem:

Given a string representing a DNA sequence, count how many of each nucleotide is present. If the string contains characters that aren't A, C, G, or T then it is invalid and you should signal an error.

The compiler is giving me the following errors:

This is due to the use of Iterator::nth. This method will call the next method on the iterator exactly n times, then stop.

It's not possible to view your link without creating an account, so I'm not sure what the problem is, but Enum.each/2 is designed to perform side effects, such as printing the values, so you don't normally care about the return value. For converting the values, you generally want Enum.map/2. For example:

QUESTION

Swift DateFormatter doesn't convert date according to preset Dateformat

Asked 2020-Jul-15 at 01:27

I came across an issue when I was doing an online exercise for Swfit on Exercism. However, the code I wrote haven't been able to pass the test suite provided by the website. The problem seems to lie with the date format of the resulting date object wrapped in an optional.

I was able to get the formate of incoming dateString to conform to the test suite date format. However, I was unable to make the destinationDate also conform to the test suite date format.

I tried to use the ISO8601DateFormatter, but the compiler on my old Mac doesn't suport this class. I tried my code on online Swift compilers, but the results haven't been satisfying so far, either.

The exercise is described as follows:

Calculate the moment when someone has lived for 10^9 seconds.

A gigasecond is 10^9 (1,000,000,000) seconds.

You are using the wrong dateFormat hh is for 01-12 hours. What you need is HH 00-23 hours. Your dateFormat should be "yyyy-MM-dd'T'HH:mm:ss". Note that Date description will return a UTC date description (not the current timezone). You would need to use the same date formatter to generate the string from the parsed date to test for equality:

Difference in types being inferred in Julia

Asked 2020-May-12 at 10:51

I am trying to learn Julia coming from Python and I came across an interesting tidbit of code on exercism.io. The user did an elegant trick of creating tuples containing functions because they are first-class objects in Julia. Building off that I wanted to try something out.

Suppose I have a list:

First note that you should use push! not append! to add one element at the end of the vector (append! appends elements of the collection to another collection). Now I will concentrate on the main issue assuming you would have used push! in your code.

All elements of code have the same type:

The task is to check if the sentence contains all letters of the alphabet. So while you can determine that is not the case (i.e. return false) when you find the first letter that is not in the sentence, you cannot state the opposite (i.e. return true) until you have checked all the letters.

Can't make sense of Exercism.io

Asked 2020-Mar-30 at 06:22

I just started out to learn Javascript and I think that coding while watching videos is the best way to master a language. I learned the following topics in Javascript (BRIEFLY): - Basic JS Operators - JS Arrays - JS Objects - If-else condition and loops

After learning these, I entered Exercism.io because I have read in some reddit comments that exercism.io is a good place for beginners to practice javascript. But I couldn't make any sense of the simple "Hello World" program in Exercism. I mean, you just write console.log("Hello World") in (most) "Hello world" programs since it a very very basic program, right? If yes, then what in the world are these:
