Insert the correct slicing syntax to print the following selection of the array:

Every other item from the entire array.

**Tip:** use the step syntax.

arr = np.array([10, 15, 20, 25, 30, 35, 40])
print(arr@(5))

arr = np.array([10, 15, 20, 25, 30, 35, 40])
print(arr[::2])

arr = np.array([10, 15, 20, 25, 30, 35, 40])
print(arr[0:0:2])
