A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the

right.

For example, we can shift the bits in the string $1011$ two places to the left to produce the string $1110.$ Note

that the leftmost two bits are wrapped around to the right side of the string in this operation.

Define two scripts, shiftLeft.py and shiftRight.py$,$ that expect a bit string as an input.

$$ The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the

rightmost position.

$$ The script shiftRight performs the inverse operation.

$$ Each script prints the resulting string.

An example of shiftLeft.py input and output is shown below:

Enter a string of bits: Hello world!

ello world!H

An example of shiftRight.py input and output is shown below:

Enter a string of bits: Hello world!

$!$Hello world
