WitrynaThe merge step takes two sorted subarrays and produces one big sorted subarray with all those elements. It just repeatedly looks at the front of the two subarrays and takes the smallest element, until it runs out of elements. It only works because the two subarrays were already sorted. In the example above (last merge) we have: Witryna29 gru 2024 · Overall time complexity of Merge sort is O (nLogn). It is more efficient as it is in worst case also the runtime is O (nlogn) The space complexity of Merge sort is O (n). This means that this algorithm takes a lot of space and may slower down operations for the last data sets . READ ALSO: Should I use MySQL workbench or phpMyAdmin?
