            How to find most common words from specific rows and column and list how often it occurs at data.csv?
            Asked 2022-Mar-03 at 20:14

            I want to get 20 most common words from the descriptions of top 10 longest movies from data.csv, by using Python. So far, I got top 10 longest movies, however I am unable to get most common words from those specific movies, my code just gives most common words from whole data.csv itself. I tried Counter, Pandas, Numpy, Mathlib, but I have no idea how to make Python look exactly for most common words in the specific rows and column (description of movies) of the data table

            When a box is clicked is grows in height to show information about the service. What I was hoping to be able to do was the "relayout" the grid so grid wrapped around the tallest item? Instead what I have is when I an item grows that row and it's children grow with it.

            What I was hoping for was if report writing was clicked it would grow and take up benchmarking space, benchmarking would move left and consultancy would wrap onto a new line?

            A couple of things.

            You can make the clicked item span two rows by setting grid-row: span 2 This will have the effect of 'pushing' other grid items around.

            matrix maximum diagonal pattern match
            Asked 2022-Jan-16 at 03:00

            I came across a problem while doing technical interviews for matrix pattern matching. I was able to solve the problem using brute force but wonder if there is a more efficient solution as I only got about half credit for efficiency. Thank you in advanced for your input.

            Given a matrix containing the numbers 0, 1, 2 and the pattern [1, 2, 0, 2, 0, 2, 0] find the max length of the matching pattern starting from any point in the matrix but can only travel diagonally.

            here is an example of where we would expect the function to return 12.

            here is where we would expect the function to return 7.

            and empty matrix should return 0.

            Here is my code, like I said previously it does work and passed all the tests but I got docked points.

            Answered 2022-Jan-15 at 22:48

            Building on the accept answer to this question. It's based on a few key ideas:

            You can use np.diagonal over a range to slice every possible diagonal out of the array. You can flip the array around to make sure you get all angles.

            You can tile the pattern to make sure it's at least as long or longer than the largest diagonal.

            You can zip the diagonal and the pattern and the extra values in the pattern will be dropped automatically due to the way zip works.

            Then you can use takewhile on the zipped (diag,pattern) to check how many consecutive matches there are len(set(x))==1.

            If you do this for all the possible combinations and take the max, you should have your answer.

            Complexity analysis for the permutations algorithm
            Asked 2021-Nov-14 at 15:07

            I'm trying to understand the time and space complexity of an algorithm for generating an array's permutations. Given a partially built permutation where k out of n elements are already selected, the algorithm selects element k+1 from the remaining n-k elements and calls itself to select the remaining n-k-1 elements:

            ...

            ANSWER

            Answered 2021-Nov-14 at 15:07

            The time complexity of this algorithm, counted by the number of basic operations performed, is Θ(n * n!). Think about the size of the result list when the algorithm terminates-- it contains n! permutations, each of length n, and we cannot create a list with n * n! total elements in less than that amount of time. The space complexity is the same, since the recursion stack only ever has O(n) calls at a time, so the size of the output list dominates the space complexity.

            If you count only the number of recursive calls to permutations(), the function is called O(n!) times, although this is usually not what is meant by 'time complexity' without further specification. In other words, you can generate all permutations in O(n!) time, as long as you don't read or write those permutations after they are generated.

            The part where your derivation of run-time breaks down is in the definition of T(n). If you define T(n) as 'the run-time of permutations(A, start) when the input, A, has length n', then you can not define it recursively in terms of T(n-1) or any other function of T(), because the length of the input in all recursive calls is n, the length of A.

            A more useful way to define T(n) is by specifying it as the run-time of permutations(A', start), when A' is any permutation of a fixed, initial array A, and A.length - start == n. It's easy to write the recurrence relation here:
