Harnny:
It's interview , simply create a variable to hold the size of your dictionary as you add. Also, in interview, you are allowed to explain the draw back of your implementations and what you will do in ideal situation.

ThrustReverser:
Op which language are you coding in?
Because I'm sure that exercise would be a cakewalk if implemented in python.
Meanwhile your codes don override flexwrap for nairaland

MT:
I dont understand the language you are using but I am not bothered about that.

What you considered a better implementation was lacking interface. You are not building a loosely coupled application this way. Where is that contract in your implementation?

Harnny:
I will still use my hashmap but use interger as the key... that value will be helpful when select a random

li2pac1717:
I think you are overthinking it bro. I believe what the interviewer is testing here is how to deal with real life problem like this. HashMap would be fine. You can create a class Lottery and explain to them that a user have to have a unique ID. So store data of the class, such as id, name, and others. That way you can use random module to pick a random id number in the range of the id and get name from the hashmap of users using the randomly picked id. I think this will be enough.

drop your mail or dm let me forward the book

richebony:
Hope u don't mind my asking, but how many programming languages do u actually know.,because I have seen u write in several languages

robinhood171200:
whatsapp? twitter? anywhwere i could text you privately.

Temmylee01:
What language is this

robinhood171200:
better luck next time bro. another opportunity will surely come. can i dm you privately or send you an email? i'd like to ask for your opinion/advice on some tech related issues.

1. add_user(string: user)
2. remove_user(string: user)
3. pick_random_winner() -> string

struct Lottery {
     map: HashMap<i32, String>,
}

impl Lottery {
    // first problem realized here, what would be the key? and i don already talk say na hash map go good for this things o chai  

    fn add_user(&mut self, string: user){
         // But this would not work it doesn't work that way. it would have made sense if the function has a signature for key.
         self.map.insert(user); error, where is the key ?  
     }

    fn remove_user(&mut self, string: user){
         //no key can't remove anything 
     }

    fn pick_random_user(&self){
         // impossible!!! no key no random - even if there was a key it doesn't  reorder it self unlike Vector. This might be possible in language like python  
     }
}

struct Lottery {
     user: Vec<String>,
}

impl Lottery {
    fn add_user(&mut self, string: user){
         // we just insert
         self.user.push(user); 
     }

    fn remove_user(&mut self, string: user){
         // linear search and then remove
        if self.participant.contains(&participant) {
            self.participant.retain(|x| x != &participant);
        }
     }

    fn pick_random_user(&self){
         let random_gen = // algorithm that generate random number
         let random = random_gen % self.user.len();
         self.user[random]
     }
}

Can't I just manually put it at the end of the script so that it will allow others to run without going through the hassle of making it asynchronous, since the whole purpose of making it asynchronous is to defer it to the end of the script?

qtguru:
See it's easier than Laravel as far as I am concerned. Plain Old Java and nothing else

Lol....u just dey after the money when work never start

Dgener:
U will at least work before u get paid

The girl is talented. But in my opinion, her voice is not too wonderful. Ayra star sings better.

airsaylongcome:
Na why I no dey reason japa laidis so. The only real draw back for me is the work hours. 5pm to 2am in my case

SUPREMOTM:
You need to calm down. CSS didn't make your life difficult, you just aren't giving yourself enough time to learn; it's always difficult before it's easy.

Ultimately, your productivity with the framework will still be limited by the depth of your knowledge of pure CSS.

While you make use of the framework, keep learning your CSS on the side.
