WebTime Complexity of Merge Sort in C#: The Merge Sort Algorithm is a recursive algorithm. The array of size N is divided into the maximum of logN parts, and the merging of all the subarrays into a single array takes O(N) time. Hence in all three cases (worst, average, best), the time complexity of Merge sort is O(nlogn). Algorithm for C# Merge Sort: WebKway merge sort would tackle this as follows Read 16Gb worth of data. Sort it. Write the sorted 16Gb of data to a temp file. Repeat steps 1-3 for the rest of the file until it now exists as a large set of 16Gb sorted temp files. Merge the sorted temp files such that the final result is sorted 1 Tb file.
