Lyrics

[Verse 1]
Sarah's building microcontrollers, memory tight as twisted wire
Every byte counts precious, cache misses fuel the fire
Arrays pack sequential, dense like sardines in a can
But linked lists scatter fragments across the memory span

[Chorus]
Choose your weapon wisely, time and space collide
Arrays for blazing access, lists when size can slide
Hash tables burn through lookups, trees keep order clean
Pick your poison perfectly for the constrained machine

[Verse 2]
Traversing costs explosion when pointers jump around
Cache lines stay empty while the processor waits profound
But insertion stays constant, no shifting elements down
Arrays force expensive moves when the collection grows its crown

[Chorus]
Choose your weapon wisely, time and space collide
Arrays for blazing access, lists when size can slide
Hash tables burn through lookups, trees keep order clean
Pick your poison perfectly for the constrained machine

[Bridge]
Custom structures shine bright when standard won't suffice
Bit-packed fields squeeze tighter, memory usage sliced
Stack-allocated arrays when bounds are crystal known
Heap fragments spell disaster in embedded zones

[Verse 3]
Profiling reveals secrets, hotspots glow like neon signs
Big-O hides the constants that cross performance lines
Real-world beats theory when cache misses multiply
Measure twice, optimize once, let benchmarks be your guide

[Chorus]
Choose your weapon wisely, time and space collide
Arrays for blazing access, lists when size can slide
Hash tables burn through lookups, trees keep order clean
Pick your poison perfectly for the constrained machine

[Outro]
Memory maps tell stories, bandwidth shapes the game
Data structure selection makes performance sing or strain
