Do not use comparator implementation like y-x.

[chabapok]

Issue in _10_Object_Expressions

Comparator implementation like y-x is wrong, because it does not work for some values. See example:

    @Test fun testSort() {
        assertEquals(listOf(5, 2, 1), sort(listOf(2, 5, 1)))
    }

    @Test fun testSort2(){
//wrong, because y-x is fail
        assertEquals(listOf(Integer.MAX_VALUE, Integer.MIN_VALUE), sort(listOf(Integer.MAX_VALUE, Integer.MIN_VALUE)))
    }


    fun sort(list : List<Int>):List<Int> {
//change to y.compareTo(x)
        Collections.sort(list, {x:Int, y:Int -> y-x} )
        return list
    }
