Merge sort using recursion in linked list
Web27 apr. 2012 · where height of tree is O (logn) => Space complexity is O (nlogn + n) = O (nlogn). However, this is not the case in the actual code as it does not execute in parallel. For example, in the case where N = 16, this is how the code for mergesort executes. N = 16. 16 / 8 / 4 / 2 / \ 1 1. notice how number of space used is 32 = 2n = 2*16 < 3n. Then ...

Web1 sep. 2024 · Merge Sort is often preferred for sorting a linked list. It is discussed here. However, the method discussed above uses Stack for storing recursion calls. This may consume a lot of memory if the linked list to be sorted is too large. Hence, a purely iterative method for Merge Sort with no recursive calls is discussed in this post. WebGiven a linked list, sort it using the merge sort algorithm. Practice this problem Merge sort is an efficient, general-purpose sorting algorithm that produces a stable sort, which means that the implementation preserves the input order of equal elements in …
