Yes using your first method, im solve alone but now i have an other problem
All code is write right but, remainder is NaN and evenOdd don't have value of "i"

function exchangeSymmetric ()
{
    var arrayPrincipal = [4, 2, 13, 0, 5];
    var array1 = [];
    var array2 = [];
    for (i = 0; i < arrayPrincipal.length; i++)
    {
        var evenOdd = array1 [i];
        var remainder = evenOdd%2;
    }
    alert (remainder);
}
