Four Bitwise Results

Read two non-negative integers a and b and print four bitwise results.

Input: two integers separated by whitespace.

Output: four lines:

AND: <a & b>
OR: <a | b>
XOR: <a ^ b>
Left Shift: <a << 1>

Example 1

Input

5 3

Output

AND: 1
OR: 7
XOR: 6
Left Shift: 10

0 <= a, b <= 1000000

Hint 1

Wrap each bitwise expression in parentheses when concatenating with a String.

Hint 2

a << 1 shifts a's bits one place to the left.

Apply &, |, ^ to the two numbers bit by bit, and << to shift a left by one bit (doubling it). Parentheses are needed so the + concatenation does not bind first.
