[Verse 1] Started coding quicksort thinking I was slick But empty arrays made my program crash quick Null pointers lurking, segmentation fault Had to learn the hard way, wasn't my fault Base case handling, that's the foundation Single element stops the recursion station Check your bounds before you start the partition Or watch your stack overflow with perdition [Chorus] Edge cases first, optimization next Duplicate keys gonna leave you perplexed Pivot selection makes or breaks your flow Worst case quadratic, that's what you don't want to know Three-way partitioning when duplicates abound Median of three keeps performance sound Remember the gotchas, avoid the trap Quicksort mastery, that's west coast rap [Verse 2] Picked the first element as my pivot choice Nearly sorted data silenced my voice Big O of n-squared, performance declined Random pivot selection cleared my mind Median of three, take the middle value Left, right, and center, let statistics guide you Hoare partition scheme versus Lomuto's way Different approaches for a different day [Chorus] Edge cases first, optimization next Duplicate keys gonna leave you perplexed Pivot selection makes or breaks your flow Worst case quadratic, that's what you don't want to know Three-way partitioning when duplicates abound Median of three keeps performance sound Remember the gotchas, avoid the trap Quicksort mastery, that's west coast rap [Bridge] Tail recursion optimization, save that stack space Iterative version puts efficiency in place Cutoff to insertion sort for small arrays Hybrid approaches, that's how the master plays Dutch flag algorithm for three-way split Equal elements grouped, performance benefits [Verse 3] Stack depth matters when recursion's deep Worst case log n, but worst case makes you weep Introsort switches when depth gets too high Heapsort fallback keeps performance fly Memory cache friendly, partition in place Locality of reference, keep up the pace Stable sort it's not, but speed's what we need Quicksort optimization, plant the right seed [Chorus] Edge cases first, optimization next Duplicate keys gonna leave you perplexed Pivot selection makes or breaks your flow Worst case quadratic, that's what you don't want to know Three-way partitioning when duplicates abound Median of three keeps performance sound Remember the gotchas, avoid the trap Quicksort mastery, that's west coast rap [Outro] From Silicon Valley to the coding scene Quicksort gotchas, keep your algorithm clean Edge cases handled, optimizations tight West coast wisdom, sorting done right
