kandi X-RAY | lcs Summary
This server provides the longest common substrings of specified strings. It produces a JSON document in response to an HTTP POST request. This project was created in August 2020 by Aaron Mansheim. It was created as an exercise to be evaluated by Todd Ricker, Senior Manager of Applications Engineering at Comcast.

QUESTION
The following data has the surprising result that it does not match. I was expecting the distance to be 5
, but even at 7
I get no match
ANSWER
Answered 2022-Apr-14 at 13:52The problem comes down to the method you are using to calculate the string distance. You are using the lcs
(longest common substring) method, which in effect only allows deletions and insertions rather than substitutions. From the docs:
The longest common substring (method='lcs') is defined as the longest string that can be obtained by pairing characters from a and b while keeping the order of characters intact. The lcs-distance is defined as the number of unpaired characters. The distance is equivalent to the edit distance allowing only deletions and insertions, each with weight one.
So when we convert spaces to underscores, we incur a weighting of 2 per substitution:
QUESTION
I'm frustrated right now. I am trying to filter data in an API and trying to push them to a useState hook array and print them to the console. I am using React and really struggling. Below is the code.
TimeChart.js ...ANSWER
Answered 2022-Apr-10 at 14:33You are wrong in using React state hook.
You can't use state variable as soon as you call setState
.
e.g. You used setTournament(xxxx); console.log(tournament);
in your code.
This is mistake.
e.g. You made a mistake to set an array in tournament
state: setTournament(lcs, lec, lpl, lck, msi, worlds);
.
You cannot set an array by passing multiple parameters.
setState
function can only accept a parameter.
You should change it by the following:

QUESTION
I was reading 'Algorithms Unlocked' by Thomas H Corman and came across an approach to finding the Longest Common Subsequence which ran in O(n * m). This approach can be seen in this article too: https://www.geeksforgeeks.org/printing-longest-common-subsequence/
This seems to be the most popular and quickest approach but seemed a bit convoluted to me so I tried to write a different approach, also using dynamic programming.
My approach is recursive, in the worst case has to branch twice every call but uses memoization to save the result of previous inputs. I understand that std::map can take lg(n) time for 'find' but I assume this code can be easily altered to use a hash map instead
...ANSWER
Answered 2022-Feb-21 at 21:30Even if you use a hashmap for memoization, and correct the bug, the time complexity is O(m*n*l)
, where l
is the length of the LCS; this is also upper-bounded by O(m*n*min(m, n))
.
First, the bug. lcs_helper
returns a string:
QUESTION
I'm trying to install slacker so I can do some SQL testing. I've never used Ruby before. I'm on Windows. My dev box only has access to the Internet via a proxy and I have to nominate all URls in advance.
I I downloaded and ran rubyinstaller-devkit-2.7.5-1-x64.exe
(because it requires Ruby 2.4/2.5+ and 2.7.X was recommended at the Ruby site) accepting all of the defaults.
When it got to MSYS2 I hit ENTER (MSYS2 base installation and MINGW development toolchain).
I got errors in the gpg section, e.g. (but not limited to)
...ANSWER
Answered 2022-Jan-16 at 16:19I have answered question 1 myself. If anyone else can give me a definitive answer to part two, I will happily mark that as the answer.
I guessed that I needed to download and install the mingw
packages that couldn't be downloaded somewhere. I did a bit of trawling and found this article (Offline installation of packages)which gave me the pointers I needed. I got these four files from https://repo.msys2.org/mingw/mingw64/:
QUESTION
I was solving a Hackerrank problem that is just a plain implementation of Longest Common Subsequence
...ANSWER
Answered 2021-Dec-29 at 21:37This is one of the classic Python blunders. You cannot initialize a 2D array using the *
operator, like x = [[0]*5]*5
. The REASON is that this gives you a list that contains 5 references to the SAME [0,0,0,0,0]
list, They aren't 5 independent lists. If you change x[0][3]
, you will also change x[1][3]
and x[2][3]
. Try setting x[2][2] = 9
and y[2][2] = 9
and notice the difference.
QUESTION
UPDATE: To solve this, I kept the checkpoint structure the same but wrote a custom train_step function, with the help of the repo linked in the accepted answer of the question linked below, which calculated the gradients and used apply_weights rather than compiling the model and using train_on_batch. This lets the full GAN state be restored. Sadly, with this method I'm fairly sure the dropout layers no longer work as the discriminator is able to work perfectly very early in the training which prevents the model from training properly. Nevertheless, the original problem is solved.
Original:
I am currently training a GAN in keras and trying to make it so that I can save the model and resume training later. Ordinarily in keras you'd simply use model.save(), however for a GAN if the discriminator and GAN (combined generator and discriminator, with discriminator weights not trainable) models are saved and loaded separately then the link between them is broken and the GAN will not function as expected. Someone asked a similar question here, How to save and resume training a GAN with multiple model parts with Tensorflow 2/ Keras, and was told to use tf.train.Checkpoint instead to save the full model at once as a checkpoint.
I've tried implementing this as follows:

Answered 2021-Nov-16 at 14:46If you have the following checkpoint structure, your model should work properly:
QUESTION
I've been putting together a UDF in Excel (365) to calculate the longest common subsequence between two strings (based on this implementation in python https://www.geeksforgeeks.org/printing-longest-common-subsequence/).
When I run the UDF I get a #Value! error on the worksheet. I've done some rudimentary debugging but I'm new to VBA and running into a wall. The message box statements in the code are simply for said crude debugging.
I believe the issue is in my manipulation of the L array. It seems to get to the first case in the first set of for loops then quit as it's evaluating L(i, j,) = 0. Any pointers on where I'm going wrong?
In the worksheet I'm using =ClosestMatch("aabbaaaa", "aaaabbaa")
and getting #VALUE!
as a result.
This is the VBA code for the UDF I'm attempting:
...ANSWER
Answered 2021-Dec-06 at 05:57The error is because the value of i= 0
on the line ElseIf Mid(x, i - 1, 1) = Mid(x, i - 1, 1) Then
which makes Mid(x, i - 1, 1)
fail and hence the function collapses.
My recommendation:
- User proper error handling always.
- Use
Line Numbers
to number your code and useERL
to get the offending line number.
Here is an example

Install lcs
You can use lcs like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
