QUESTION
I want to write a simple desktop application to track the overtime work of our employees. Whenever one of our employees needs to perform some tasks outside our normal working hours we want to track them using "Kimai Time Tracking".
The application I am programming needs to get the duration of all recorded tasks from Kimai, add them up and store them on a local SQL Server as an overtime contingent for the employee to claim later.
This is the GET request I'm mainly gonna use:
GET /api/timesheets (Returns a collection of timesheet records)
and this is an example output from the Kimai Demo (Sorry for length)

QUESTION
I have been looking at the application of merge sort to linked lists. Some of the articles I have looked at tout that merge sort is the best algorithm for sorting a linked list. It makes sense for the conquer part in the divide and conquer strategy where you merge the two sorted linked lists as you end up saving on required memory (compared to an array). But, what I don't understand is the time complexity of the divide step in the algorithm.
For an array, this step is constant time by leveraging random access and splitting the array into smaller chunks. But, for a linked list isn't this going to take an additional O(n)? I have seen Floyd's algorithm (tortoise-hare) used to find the mid-point of a linked list and divide the problem into smaller chunks. I did some analysis on the divide step. Suppose the linked list is of size n, then the # of operations involved in just dividing the problem is as follows,
n/2 + n/4 * 2 + n/8 * 4 + ... = n/2 * log(n)
From the above, it looks like compared to the array case, an additional factor of "n" appears from Floyd's algorithm. So, the final time complexity would be O(n^2 * log(n)). Can someone please explain the discrepancy?
Edit: based on @Yves comment, I identified the mistake,
I multiplied the work while merging back the sorted blocks from bottom to top when it should be added. So, the net time would be: nlogn/2 + nlogn = O(nlogn),
This is probably is most valid answer to the above question; other answers are a bit indirect/ provide no explanation
...ANSWER
Answered 2021-May-22 at 21:29The issue with your question is that the additional O(n/2) time complexity for the scanning of half a sub-list for each level of recursion translates into an overall time complexity of O((0.5 n log(n) + 1.0 (n log(n)) = O(1.5 n log(n)), not O(n^2 (log(n))), and O(1.5 (n log(n))) translates into O(n log(n)), since time complexity ignores lower order terms or constants. However in my actual testing for a large list with scattered nodes, where most node accesses result in a cache miss, my benchmarks show an relative time complexity of recursive versus iterative to be O(1.4 n log(n)), using a count based scan to split lists, rather than tortoise-hare approach.
For recursive version, using tortoise-hare approach is relatively slow and can be improved by using a count of nodes, which may require a one time scan of n node if the linked list container doesn't maintain a count of nodes (for example C++ std::list::size()). The reduces the overhead to advancing a single pointer halfway (sub-count / 2) through a linked list run.
Example C / C++ code:
Time taken to sort numbers in Linked List
However, in such a case (large list, scattered nodes), it is faster to copy the data from the list into an array, sort the array, then create a new sorted list from the sorted array. This is because elements in an array are merged sequentially (not via random linked list next pointers), which is cache friendly.

I have the following code. Its same as the basic table from material ui. Only thing i have modified the First row, second column content. I am using a Grid element inside it. and also added more columns so that i can see a horizontal scroll scenario

I'm not very knowledgeable in R but know a reasonable amount about a few other languages and have a solution to this but I want to know if there is a more efficient way as I plan to use this for large lists. I've looked online a few times and tired various things with no luck, this answer may be the answer but I cant seem to make it work.
I have a list of strings from an external file, each potentially with a different number of characters in each element. I would like to pad this list (with trailing white space) so that all elements have the same length. I’ll use ‘+‘ in place of white space in the example for clarify. So
