WebGiống như Quick sort, Merge sort là một thuật toán chia để trị. Thuật toán này chia mảng cần sắp xếp thành 2 nửa. Tiếp tục lặp lại việc này ở các nửa mảng đã chia. Sau cùng gộp các nửa đó thành mảng đã sắp xếp. Hàm merge () được sử dụng để gộp hai nửa mảng. WebMerge Sort time complexity is calculated using time per division stage. Since the merge process has linear time complexity, for n elements there will be n * log~2~n n ∗ log 2 n division and merge stages. Hence, …
