//необходимо реализовать функцию позволяющую делать сдвиг массива
//@param swift - любое целочисленное число
//@param arr - любой целочисленный массив
//func arrayShift(_ arr: [Int], swift: Int) -> [Int]
//пример 1
//arrayShift([1,2,3,4,5], shift: 1)
//result : [5,1,2,3,4]
//пример 2
//arrayShift([1,2,3,4,5], shift: 2)
//result : [4,5,1,2,3]
