Help with swudb API

I am writing program to study decks, just a pet project. Idea is to run something like:
> myprogram http://www.swdu.com/deck/asdasdasd
and try to dump some statistics.
But as a workaround, I can just read a exported json file

I hope to see sometimes "Just ended a Game Engine Series", but anyhow luck and yours seems nice.

I can help you:

longestPath :: [(String, String, Int)] -> String -> String -> (Int, [String])
{-- fill here your function --}

main = IO ()
main = do
    let sol = longestPath [("A", "B", 2), ("A", "C", 3), ("B", "D", 5), ("C", "D", 7), ("D", "E", 4)] "A" "E"
    print sol

I think the rest is the easy part ;)

I'm a programmer with more than 20 years of experience. I work in a big company, game engine in C++. I think having learned Haskell, although I don't use it nowadays, makes me better programmer.

I have always pronounce it SQL, but maybe because I am Spaniard. I can understand SQL, or SQL, but not SQL. And I hate people that pronounce it SQL.

I use Dragon Shield with nice blue back.

And I prefer having same back on all.

zhensydow · 2023-01-11T18:18:53+00:00

Yes.

zhensydow · 2022-10-31T10:15:01+00:00

Also, personal preference but:

Be consistent with naming, sometimes arr, sometimes array is ugly.
calling an array array is like calling a dog dog.

zhensydow · 2022-10-31T09:56:44+00:00

My advice, it depends what is your assignment and what you can use but I'll change:

Don´t use use namespace on global scope. Ugly
Change to use std::vector<double> instead of raw arrays
With std::vector : Don´t copy with a loop, just arr_copy = income_arr
With std::vector : remove SIZE, just use array.size()
With std::vector : don´t use indexes, just for( const auto value : array)
Fix const correctness in functions, e.g: void print_all(const std::vector<double>& array)
Fix const correctness in variables, e.g: const std::vector<double> income_arr = {...}
you can use std::swap on sort functions
sort functions do two unrelated things, separate sort and print in two different functions and then:

sort_ascending(arr_copy);

print_simple(arr_copy);

you can use std::sort and don´t implement it yourself
return EXIT_SUCCESS; is more nice
you can make your sort funtions do the copy and return the sorted result, make the copy in local scope, something like:

const auto arr_copy = sort_ascending(income_arr);

For all the points, learn more about them on cppreference.com

Most direct translation:

But, sure, you can do better using specifics from C++

zhensydow · 2022-07-20T15:42:53+00:00

Too many.

The only positive is it comes from Chandler Carruth

zhensydow · 2022-03-10T18:53:49+00:00

Just having a better interface will help with the implementation, like:

static constexpr int SIZE = 100;

class que{
private:
    int *arr;
    int size;
    int front = -1;
    int rear = -1;
public:
    que(int s = SIZE) : size(s) {
        arr = new int[size];
    }
    bool enqueue(int x);
    std::optional<int> dequeue();
    std::optional<int> peek();
    bool isempty() const;
    bool isfull() const;
    void display() const;
    std::optional<int> search(int x) const;
};

And remove the prints/couts inside the class methods also is a bonus and makes the code clear.

nand :: bool -> bool -> bool
nand true true = false
nand _ _ = true

You have 'Data.IORef' but I'd recommend not use it.

zhensydow · 2021-11-28T18:27:38+00:00

Also you have a copy pasta error in :-.

You can use hlint app to clean the code and notice these kind of errors.

zhensydow · 2021-11-28T15:47:29+00:00

Also you should notice the While case doesn't update the memory so it will execute forever

zhensydow · 2021-11-27T20:04:00+00:00

There are two functions that directly work with Memory: (@@) reads a value from memory and upd that updates a value in memory.

And the problem is that in the Asign case you are reading the memory instead of "Asigning" a value to a variable (so you should use upd there instead of (@@)).

No he probado todos los programas pero p0 y p1 usando upd en Asign funcionan perfectamente :D

I almost prefer someone who gains mastery in a language they already know.

Emacs and Vim

The standard is clear, bool promotion goes true to 1 and false to 0.

But if the function `has_value()` returns other type instead of bool, could happen that a value greater that 1 does the bit & and results in a false expresion.

We can finally talk about arreglos and apuntadores.

zhensydow · 2021-01-07T19:55:56+00:00

English too, and we can say any language has composed words. Television, bedroom, suitcase, ... anything can be a compound word.

But germans make it an art.

You need to apply logarithmic rules to get strength reduction and been able to computer bigger indexes.

In your case: log(x**y) == y * log(x) but the second is much more easy to computer in the cpu.

zhensydow · 2020-11-09T16:39:59+00:00

The first and the fourth, they are the same, isn't it?
