Lyrics

[Verse 1]
Down in the depths where the zeros and ones live
Every bit has a story to give
AND operation keeps what's common and true
OR brings together me and you
XOR flips when they're different inside
NOT inverts every bit far and wide

[Chorus]
Shift left multiply, shift right divide
AND for masks, OR to combine
XOR to flip, NOT to invert the line
Bits are dancing in perfect time
Left shift doubles, right cuts in half
Bitwise magic, do the math

[Verse 2]
When you need to check a single bit's state
Use AND with one, don't hesitate
To set a flag, OR with one will do
Clear a bit, AND with zero's true
Toggle switches with XOR's might
Flip that bit from dark to light

[Chorus]
Shift left multiply, shift right divide
AND for masks, OR to combine
XOR to flip, NOT to invert the line
Bits are dancing in perfect time
Left shift doubles, right cuts in half
Bitwise magic, do the math

[Bridge]
Rotation keeps the bits in play
Circular motion, none drift away
Left rotate brings the high bits low
Right rotate makes the pattern flow
Masks reveal what you want to see
Filter data efficiently

[Verse 3]
Count the ones with Brian Kernighan's way
AND with minus one, bits fade away
Two's complement flips then adds one more
Negative numbers at the core
Sign extension fills the space
Higher bits maintain their place

[Chorus]
Shift left multiply, shift right divide
AND for masks, OR to combine
XOR to flip, NOT to invert the line
Bits are dancing in perfect time
Left shift doubles, right cuts in half
Bitwise magic, do the math

[Outro]
From the lowest level up we climb
Every bit keeps perfect time
Optimization starts below
Where the binary rivers flow
