QUESTION
I'm choosing the middle point as the pivot but I'm not sure that matters.
If the pivot is the minimum value in the set it does not work correctly.
How can I pick a pivot so that I can correctly create a partition for later use in the quick sort algorithm?
...ANSWER
Answered 2018-Mar-15 at 00:36Don't keep an index for the pivot, keep the pivot element value so that you can still compare to it even when it gets swapped around:
QUESTION
I want to partition an array (eg [1,2,3,4,5,6,7,8]
), first partition should keep even values, second odd values (example result: [2,4,6,8,1,3,5,7]
).
I managed to resolve this problem twice with built-in Array.prototype
methods. First solution uses map
and sort
, second only sort
.
I would like to make a third solution which uses a sorting algorithm, but I don't know what algorithms are used to partition lists. I'm thinking about bubble sort, but I think it is used in my second solution (array.sort((el1, el2)=>(el1 % 2 - el2 % 2))
)... I looked at quicksort
, but I don't know where to apply a check if an integer is even or odd...
What is the best (linear scaling with array grow) algorithm to perform such task in-place with keeping order of elements?
...ANSWER
Answered 2017-Jul-14 at 23:45let evens = arr.filter(i=> i%2==0);
let odds = arr.filter(i=> i%2==1);
let result = evens.concat(odds);
