QUESTION
I want to delete the leaf nodes, the values of which are outside a given range (say [L R]). I made a solution in which I was simply traversing all the nodes and checking if my current leaf node's value is in the given range or not. If it is not then I'm removing this node.
My approach -
...ANSWER
Answered 2021-Jun-10 at 13:37Like m.raynal said, since you only want to remove leafs you can't get better than O(n).
You only can add a shortcut when all the nodes in the branch will be inside the range, something like

ANSWER
Answered 2021-Jun-07 at 10:39The regex you wrote at the online regex testing site is wrong. You are tricked into believing it works by the [\d{2}[^0-9]
character class that actually matches a digit, {
, 2
, }
, [
or ^
(with the PCRE/JS regex settings).
You must remember to escape the [
literal char, and remove the .\\d{2}
part as there are no extra two digits at that location in your sample strings.
So, you may use
QUESTION
I want to write a psudo-code to find the distance between 2 nodes in a BST.
I have already implemented LCA function.
Here is my attempt:
...ANSWER
Answered 2021-Jun-06 at 11:34Finding the LCA is helpful, but you could determine the length of the path while determining the LCA.
I would first define a helper function which will give the path from the root to the given node. As the root is the only node without a parent, we don't actually need to provide the root to this function:

Confused about the BST tree drawing, say you want to insert the values 12, 9, 4, 6, 5, 15, 14, 16, 17, 18 into an empty binary search tree in the given order without balancing. What will the tree be like after each insertion? And what will happen to the tree if the value 12 is deleted?

I tried using the following in crontab:
...ANSWER
Answered 2021-Jun-03 at 16:27Posting my findings as an answer since it's too large for a comment.
Lets take a look at the error shown by systemctl status apod
after boot:
urllib2.URLError:
This implies that the requests.get()
call fails.
This makes sense, since your systemd script is called before the machine has an active network connection. Therefore, the request will always fail, resulting in an error.
I'd recommend adding an Wants
/ After
network-online.target
to ensure the systemd script is started when the machine has an active network connection:
QUESTION
Hi I am a beginner and learning DSA now. This program is to validate a bst. In the image attached all the left nodes are lesser than their root node and all the right nodes are greater than the their root node. But expected output is false according to the compiler(leet code) and i dont understand why. Can someone explain this to me pls. Also please find below my code.
...ANSWER
Answered 2021-Jun-02 at 19:16The tree is not valid because you have a leaf on the right side that is less than the root. Even though it is on the left of its parent, which is correct, everything to the right of the root must be greater than the root.

How can I search for an element in a binary tree that is not a bst?
This is an example of how my tree looks
...ANSWER
Answered 2021-May-27 at 15:27You're missing return statements for your recursive calls. So not only does the recursion continue, but the value is never returned to the original caller.
QUESTION
I trained a XGBoost model using AI Platform as here.
Now I have the choice in the Console to download the model, as follows (but not Deploy it, since "Only models trained with built-in algorithms can be deployed from this page"). So, I click to download.
However, in the bucket the only file I see is a tar, as follows.
That tar (directory tree follows) holds only some training code, and not a model.bst
, model.pkl
, or model.joblib
, or other such model file.
Where do I find model.bst
or the like, which I can deploy?
EDIT:
Following the answer, below, we see that the "Download model" button is misleading as it sends us to the job directory, not the output directory (which is set arbitrarily in the codel the model is at census_data_20210527_215945/model.bst
)
ANSWER
Answered 2021-May-28 at 05:48Only in-build algorithms automatically store the model in Google Cloud storage.
In your case, you have a custom training application. You have to take care of saving the model on your own.
Referring to your example this is implemented as listed here.
The model is uploaded to Google Cloud Storage using the cloud storage client.

I'm building a little k8s controller based on the sample-controller.
I'm listening for ServiceAccount events with the following event handler:
...ANSWER
Answered 2021-May-27 at 17:35SampleController is not the most easy code to deal with. They have example on how they cast objects to a known resource type. And they also have example on how they lookup the resource from a lister.
Unless you have specific needs, I would recommend to also consider using kubebuilder and follow the kubebuilder book that has intuitive explanations of making controllers.

I have trained a model using the pix2pix pytorch implementation and would like to test it.
However when I test it I get the error
...ANSWER
Answered 2021-May-26 at 11:04I think the problem here is some layer the bias=None
but in testing the model required this, you should check the code for details.
After I check your config in train and test, the norm
is different. For the code in GitHub, the norm difference may set the bias term is True or False.
