polyphase

hich allows for an optimized merging process with fewer total passes. The key idea behind polyphase merge sort is to leverage multiple auxiliary files to perform a sequence of merges that systematically reduce the number of runs until the entire dataset is sorted. Unlike the traditional merging ap
