QUESTION
I am trying to get better understanding of Tarjan's algorithm for finding SCC, articulation points and bridges. I am considering a special case where the graph contains only 2 nodes with edges 0->1 and 1->0. The following code will output [0,1] as a bridge.
...ANSWER
Answered 2022-Apr-05 at 09:27A bridge in a directed graph is an edge whose deletion increases the graph's number of strongly connected components, and the number connected components when the graph is undirected. So when you remove any edge in your graph then the number of strongly connected components increases so the output of this code is correct in this case.

QUESTION
I want to extract struct's map members' tag with reflect, while I found if retrieve member's value from MapIndex, the type of it will be recognized as "*interface{}" and hence all type information are lost, no mention reflect can extract detail information.
...ANSWER
Answered 2022-Mar-16 at 13:56As you know using &theValue
resolves to the type *interface{}
. The type *interface{}
is distinct from the type *Student
which is what you are passing in to traversalTag
from tryMapWithType
.
If you want to pass *Student
to traversalTag
from tryMapWithReflect
you need to create that pointer value using reflection. Plain native Go address operator &
just isn't enough.
When you have a reflect.Value
that is addressable all you need to do is to call the .Addr()
method to get a pointer to the addressable value, however map elements are not addressable and therefore reflectMap.MapIndex(key)
is not addressable. So, unfortunately for you, it's not possible to do reflectMap.MapIndex(key).Addr().Interface()
to get *Student
.
So your only option is to use reflection to create a new value of the *Student
type, set the pointed-to value to the value in the map, and then return the .Interface()
of that.
QUESTION
Struggling to wrap my head around this.
Maximum Subarray Easy Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.
A subarray is a contiguous part of an array.
Example 1:
Input: nums = [-2,1,-3,4,-1,2,1,-5,4] Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6. Example 2:
Input: nums = [1] Output: 1 Example 3:
Input: nums = [5,4,-1,7,8] Output: 23
...ANSWER
Answered 2022-Mar-15 at 20:20class Solution:
def maxSubArray(self, nums: List[int]) -> int:
for i in range(1, len(nums)):
if nums[i-1] > 0:
nums[i] += nums[i-1]
return max(nums)
QUESTION
I'm starting to solve some questions on recursion, where I noticed the need of having a shared variable (such as a set/list) to append (or add in case of a set) results to and return. I searched online and found some solutions, which seem to work for me in some cases and not in others - I tried global variables, lists defined outside the recursive functions and so on.
I'm unable to understand why it works in certain cases and doesn't work in others (maybe I'm missing how the recursion calls are working?)
...ANSWER
Answered 2022-Mar-07 at 06:04You should avoid persistent state whenever possible. And you should particularly avoid global persistent state. If your recursive function uses a global container, you will only be able to call it once; after that, the global container is contaminated with data from the first call.
Note that using a container as a default argument is effectively the same as using a global variable, with one additional fatal flaw: unlike real global variables, which could in theory be reset, there is no convenient way to reset a default argument specification. When you write:
QUESTION
I came across the following problem.
...ANSWER
Answered 2022-Mar-04 at 03:58The reason you're getting a memory limit exceeded is the arguments to the dfs
function. Your 'path' variable is a string that can be as large as the height of the tree (which can be the size of the whole tree if it's unbalanced).
Normally that wouldn't be a problem, but path + "L"
creates a new string for every recursive call of the function. Besides being very slow, this means that your memory usage is O(n^2)
, where n
is the number of nodes in the tree.
For example, if your final path is "L" * 1000
, your call stack for dfs
will look like this:

According to the writing docstrings tutorial of Sphinx, it is possible to utilize Sphinx's autodoc
extension to automatically generate documentation. We can either write docstring with the Sphinx
format, Google
or Numpy
(the latter two with the napoleon
extension).
Is it possible to write docstrings in reStructuredText format?

QUESTION
I have always resisted using asyncio
within my code, but using it might help with some performance issues that I'm having.
Here is my scenario:
- An end user provides a list of news sites to scrape
- Each element is passed to an
Article Class
- A valid article is passed to an
Extraction Class
- The
Extraction Class
passes data to aNewsExtraction Class
90% this of the time this flow is flawless, but on an occasion one of the 12 functions in the NewsExtraction Class fails to extract data, which exist in the HTML provide. It seems that my code is "stepping on itself," which cause the data element not to be parsed. When I rerun the code all the elements are parsed correctly.
The NewsExtraction Class has this function get_article_data_elements
, which is called from the Extraction Class.
The function get_article_data_elements
call these items:
ANSWER
Answered 2022-Jan-31 at 00:54Your are defining _extract_article_published_date
and get_article_data_elements
as coroutines, and this coroutines must be await
-ed in your code to get the result of their execution in an asynchronous way.
You can do this creating an instance of type NewsExtraction
and calling this methods with the keyword await
in front, this await
pass the execution to other task in the loop until his awaited task completes its execution. Note that there are no threads or process involved in this task execution, the execution is passed only if it is no using cpu-time (await
-ing I/O operations or sleeping).
QUESTION
very menial question, but is there a reason that this works
...ANSWER
Answered 2022-Jan-15 at 14:16It is not because of the let punning but because of the type-driven record field names disambiguation. It is not principal and there is even a warning that tells you that your code depends on its presence. In the first case, the typechecker infers the type of the function from the application. In the second case, it doesn't have the type of information to infer that somefield
comes from the module R
1.
In OCaml, the field names are defined in the namespace of the module, so it is better to specify the module name explicitly, e.g.,
