# сортировка – Sort array by multiple conditions

## Question:

Input: array of integers( `-2^31 <= n < 2^31` )

Output: an array of numbers sorted in the following order:

• non-negative even
• negative odd
• non-negative odd
• negative even

If several numbers fall into one group, then sort them in ascending order

This is code golf, but no answer will be accepted. the purpose of the question is to compile a short solution in each language

# perl 56

I don't like to support the myth that perl is the most obscure language, but…

``````\$,=", ";
@X = (-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5);
print sort{(\$a<0^\$a&1).(\$a<0)cmp(\$b<0^\$b&1).(\$b<0)||\$a<=>\$b}@X;
``````

The sort function sorts the array specified at the very end ( `@X` ) with a block of code before it. In this block, the predefined variables `\$a` and `\$b` containing the compared values ​​are available. the task of the block is to calculate which of them is greater.

``````sort {
Выражение1 cmp Выражение2   # Лексикографическое сравнение двух выражений
||                          # ИЛИ (если они равны)
\$a <=> \$b                   # Числовое сравнение самих переменных
} @X;
``````

Now the expression itself for evaluating the weight of a variable:

``````( \$a<0 ^ \$a & 1 )   # XOR между значениями признака отрицательного числа и его четности (младшего бита)
# он равен 0 для неотрицательных четных и отрицательных нечетных, иначе 1
.                   # Конкатенация строк
( \$a<0 )            # признак отрицательности
# в perl сравнение дает пустую строку если условие ложно или 1 если истинно
``````

At the output, this expression gives the strings: "0", "01", "1", "11". In lexicographic order, these lines give the order of conditions we need.
