Add Practice Exercise: wordy

[0xNeshi]

Problem specification:
https://github.com/exercism/problem-specifications/tree/main/exercises/wordy

TODO:

• generate the exercise with ./bin/fetch-configlet && ./bin/configlet create --practice-exercise wordy
• check if any of the existing tracks (examples below) implement the exercise and you can reuse the implementation:
  • Go: https://github.com/exercism/go/tree/main/exercises/practice
  • Rust: https://github.com/exercism/rust/tree/main/exercises/practice
  • Python: https://github.com/exercism/python/tree/main/exercises/practice
• use exercise's canonical-data.json to see which test cases to implement:

Let me take this.

Hi @0xNeshi

I've been facing some difficulty manipulating strings especially in the area of comparing a fraction of sentence. In the meantime, can I take another task that I can quickly solve the practice exercise.

Just wanted to update you on the progress of this particular issue.

@Ephraim-nonso imo the most straightforward solution is Go's, and it being fairly imperative, it is the most easily translated to Cairo.

You can always split a sentence into words with the following pseudocode:

words = []
current_word = ""
for ch in string {
    if ch != empty_space {
        // in Cairo, use ByteArray::append_byte to convert ASCII number to actual ByteArray char
        current_word += ch 
    } else {
        // we got to the end of the current word, we can append it to the array
        words.append(current_word)
        current_word = ""
    }
}
words.append(current_word) // last "word" should be the '?' char, and we append it as well

After this, the algorithm is pretty much the same is in Go's implementation and string comparison should be easier as well.
It's not particularly clever, but it doesn't have to be. We aim for ease of understanding and idiomatic Cairo code.

If you still think you'd like to work on something else, I think the easiest tasks would be to add Concept exercises, they are mostly at the top of the issues list. You can choose any other issue to work on as well, there are still many other practice exercises and even some concepts to be written as well. Let me know what you'd like to work on, and I'll reassign you.

Alright. I'd revisit while putting this into consideration.
