切片一个数组的中间部分

arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sliced_arr = arr[2:8]
print(sliced_arr)  # 输出 [3, 4, 5, 6, 7, 8]

int[] arr = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int[] slicedArr = Arrays.copyOfRange(arr, 2, 8);
System.out.println(Arrays.toString(slicedArr));  // 输出 [3, 4, 5, 6, 7, 8]

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const slicedArr = arr.slice(2, 8);
console.log(slicedArr);  // 输出 [3, 4, 5, 6, 7, 8]
