TASK:Write an additional function to perform a bitwise left shift or a bitwise right shift using the bitwise operators << and >>.
Check that performing a left shift by n place(s) is equivalent to multiplying a number by 2n.
For instance 5 << 3 is the same as 5×23 = 40.
Check that performing a right shift by n place(s) is equivalent to dividing a number by 2n (whole division).
For instance 40 >> 3 is the same as 40/23 = 5.
