[Verse 1] Started with a problem, array's looking messy Need to sort it clean, algorithm's my destiny Mergesort's the answer, divide and conquer flow Split it down the middle till there's nowhere left to go Base case is the key, when you got just one Single elements sorted, that battle's already won Recursive calls breaking down the structure Clean and elegant code, that's the programmer culture [Chorus] Divide divide divide until you can't divide no more Conquer conquer conquer as you build back from the floor Merge merge merge those sorted halves together O of n log n complexity, stays stable in all weather Split it down, build it up, that's the mergesort way Guaranteed performance every single day [Verse 2] Two pointers dancing, left array and right Compare the elements, take the smaller sight Copy to temp storage, keep the order tight Linear merge process, everything's alright Stable sorting method, equal elements stay In their original order, that's the proper way Space complexity linear, need that extra room But time stays logarithmic, performance in full bloom [Chorus] Divide divide divide until you can't divide no more Conquer conquer conquer as you build back from the floor Merge merge merge those sorted halves together O of n log n complexity, stays stable in all weather Split it down, build it up, that's the mergesort way Guaranteed performance every single day [Bridge] Recursive tree structure, height is log of n Each level does n work, multiply again Best case worst case average, all the same result Predictable performance, that's the main adult Unlike quicksort gambling with that pivot choice Mergesort's consistent, let me hear your voice [Verse 3] Bottom up approach if recursion ain't your style Iterative merging, going mile by mile Start with single elements, merge them two by two Double up the size until the whole array's through Parallel potential, divide the work around Multiple processors working, fastest sort in town Industry standard algorithm, proven through the years Mergesort's the champion that never disappoints or steers [Chorus] Divide divide divide until you can't divide no more Conquer conquer conquer as you build back from the floor Merge merge merge those sorted halves together O of n log n complexity, stays stable in all weather Split it down, build it up, that's the mergesort way Guaranteed performance every single day [Outro] When the data's critical and you need it sorted right Mergesort's your weapon in the algorithmic fight Divide and conquer master, merge those pieces clean Most reliable sorting that you've ever seen
