You divide the array in half log (n) times, and each time you do, for each segment, you have to do a merge on two sorted array. Merging two sorted arrays is O (n). The algorithm is just to walk up the two arrays, and walk up the one that's lagging.

"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: " - Is merge sort always nlogn

Witryna13 mar 2024 · Asymptotically, merge sort always takes O (n Log n) time, but the cases that require more comparisons generally take more time in practice. We basically need to find a permutation of input elements that would lead to maximum number of comparisons when sorted using a typical Merge Sort algorithm. Example: Witryna3 maj 2012 · To visualize 'n log n', you can assume the pivot to be element closest to the average of all the elements in the array to be sorted. This would partition the array …

Witryna16 mar 2024 · All we have to do is merge them together, which takes n operations. On the next-to-last iteration, we have twice as many pieces (4) each of size n/4. For each of our two pairs of size n/4, we merge the pair together, which takes n/2 operations for a pair (one for each element in the pair, just like before), i.e. n operations for the two pairs. Witryna14 paź 2013 · It always works out to O (n log n). The runtime difference will be in the merge method. Merging sorted lists is an O (n log k) operation, where n is the total number of items to be merged, and k is the number of lists. So merging two lists is n * log (2), which works out to n (because log2 (2) == 1 ).
