JavaScript oneliners for the win!

const superSize = n => +n.toString().split('').sort((a, b) => b - a).join('')

REPLY

George W Langham

Had a feeling it was this simple.

Why the plus though?

REPLY

Craig McIlwrath

The argument to the unary plus operator is a string. The + is a very concise method of converting a string to a number, in this situation.

THREAD

George W Langham

Ah, I totes prefer the readability over conciseness approach

REPLY

エラリー　ジャンクリストフ

emacs lisp is shorter than common lisp (no need to "extract" the first value of parse-integer)

(defun superSize (n) (string-to-number (seq-sort #'> (number-to-string n))))

and has as few parens as @savagepixie 's JS solution :-)

REPLY

in C++ using the standard template library:

typedef unsigned long long ull;
ull superSize(ull x) {
    vector<short> d;
    while(x > 0) {
        d.push_back(x%10);
        x /= 10;
    }
    sort(d.begin(), d.end(), greater<short>());
    ull r = 0;
    for(auto i: d)
        r = r*10 + i;

    return r;
}

REPLY

dart

int superSize(int number) {
  var data = number.toString();
  var dataInt = List<int>();
  for(var n = 0; n < data.length; n++) {
    var val = int.tryParse(data[n]);
    if(val != null) {
      dataInt.add(val);
    }
  }
  dataInt.sort((a, b) => b.compareTo(a));
  return int.tryParse(dataInt.join());
}

I'm sure this could be done shorter.

Jehiel Martinez

In JS, implementing Bubble Sort just because.

function superSize(num) {
    let str = [...num.toString()];
    let swap;
    do {
        swap = false
        for (i = 0; i <= str.length; i++) {
            if (str[i] < str[i + 1]) {
                const bigger = str[i + 1];
                str[i + 1] = str[i];
                str[i] = bigger;
                swap = true
            }
        }
    } while (swap);
    return(+str.join(''));
};

REPLY

Javascript

const superSize = n => {
    const nArr  = Array.from(n.toString()).map(Number);

    const nArrSorted = nArr.sort((a, b) => b - a);

    return parseInt(nArrSorted.join(''));
};

REPLY

Javascript solution for superSize :)

function superSize(number){
let revNum = "";
let tempNum = number;
while(number != 0){
    revNum = `${revNum}${(number % 10)}`;
    number = parseInt(number / 10);
}
revNum = parseInt(revNum);
return revNum > tempNum ? revNum : tempNum;
}

REPLY

Valts Liepiņš

Yet another Ruby one liner:

def superSize int
    int.to_s.chars.sort.reverse!.join.to_i
end

Also neat how it reads almost literarly, no need to explain each step in the chain!

REPLY

Scala

def superSize = (_ : Int).toString.sorted.reverse.mkString

REPLY

Craig McIlwrath

Haskell:

import Data.Char (digitToInt) 
import Data.List (sortBy) 
supersize :: Int -> Int
supersize = read . sortBy (flip compare) . map digitToInt . show

common lisp

(defun superSize (n) (car (list (parse-integer (sort (write-to-string n) #'char>)))))

parse-integer outputs 2 values but we only need the first, hence the hack with (car (list...)

Top 5 Soft Skills for Software Engineer

Soft skills are as critical as technical skills for a software engineer. No one works in isolation. Each person has to deal with teammates, colleagues, managers, etc. Therefore team interpersonal skills are essential too. Soft skills include things like good communication, honesty, teamwork, integrity, organization, empathy, etc.
