QUESTION
I was checking "minimum number of jumps to reach the end" problem in GeekforGeeks https://www.geeksforgeeks.org/minimum-number-of-jumps-to-reach-end-of-a-given-array/ . I got confused about the time complexity mentioned there which is O(n^n).
...ANSWER
Answered 2021-Jun-15 at 07:34I can see the recurse relation as T(n) = T(n-1) + T(n-2) + T(n-3) + T(n-4) + ... + T(0)
, since the loop is from l to h (ignore the if
condition for now). So for an interval [l,h]
every value in that interval will be called in the worst case that is minJumps(l+1, h), minJumps(l+2, h) ... minJumps(h, h)
and it can be noticed that the above recurse relation holds here.
Now, solving the relation, we can write it as T(n) = T(n-1) + T(n-1)
as T(n-1) = T(n-2) + T(n-3) + T(n-4) + ... + T(0)
. Hence T(n) = 2 * T(n-1)
which boils down to O(2^n)
.
The time complexity of the mentioned algorithm should be O(2^n)
.

QUESTION
I'm working on a 2D game in Unity and am using the A* Pathfinding Package from Aron Granberg.
Everything appears to be working fine. AIPaths are being generated and AI Agents are navigating from point to point and avoiding obstacles as expected. It's fine except for one thing.
The position.z
of the AI Agent is incorrect.
The spawn origin of the AI Agent has a z of 0, and the target point has a z of 0, yet the AI Agent's z fluctuates between -9 and -1 as it traverses the path. The path itself appears to have a z position of 0 at each waypoint.
I haven't modified the code in the package at all and just followed the documentation when setting it up for 2D.
Any ideas what could be causing this?
NOTE: I haven't included a screenshot of it, but the prefab that is being spawned in as the AI Agent has a transform position of (0,0,0).
The A-star pathfinder object:
The AI Agent object (note that the Z pos is not 0):
The spawn point object that sets the spawn for the AI agent:
The destination target object that the AI Agent is heading to:
...ANSWER
Answered 2021-Jun-14 at 02:09In case anyone else runs into this problem.
The fix was to add a Rigidbody2D to my AI Agent and set the gravity scale to 0.
Even though my game doesn't use Unity's physics system for movement and the Astar package can move AI agents by transform, for some reason it requires a Rigidbody to keep the Z position at 0.
I'm still not really sure why this solves the problem because, when I was debugging the third-party Astar code, it always returned nextPosition values with a Z position of 0 yet the actual position that the AI Agent was updated to had varying Z positions...
If you have more info, leave a comment and I'll add it to the answer.
QUESTION
Consider this code:
...ANSWER
Answered 2021-Mar-12 at 12:54Try not not imagine as "array traversing", but follow what does the for loop actually do: You declare a variable i
and increment it after every iteration and using it to access the arrays. For the outer array, you say "give me first, second, third, ... element" (a[i]
). That's equivalent to for each in lists - you go over all elements of the outer array. But on the result (inner array), you access i
th element again (a[i][i]
) - which means that you're not iterating over every element of the inner array, but just one - first element of the first array, second element of the second array etc.

I want to write a recursive function to traverse symbolic links from source path to destination path
Example: 1)readlink patha/pathb/pathc -> gives if symbolic link exists 2)readlink patha/pathb/pathc/ -> gives if symbolic link exists
I'm using os.readlink method in python to get symbolic link in Python but how to traverse multiple symbolic links
Reason for traverse:
If its in future someone wants to add file3 symbolic link in between , then I wanted a recursive function to traverse each symbolic links and gives the final dest path
file1 -> file2 -> .... -> for getting destination path

QUESTION
I've read in many places that finding the size of a tuple in Elixir is really fast because tuples are stored in contiguous memory cells. However, for lists is more expensive to do because one needs to traverse the whole list to know the length of the list.
I don't understand how by being in contiguous memory cells, finding out the size of a tuple will be faster. Don't you have to go through each cell too?
...ANSWER
Answered 2021-Jun-09 at 04:10The tuple size is stored. The length of the list is not.
A tuple is also a boxed value, so it consists of a Boxed pointer (1 word) to an
ARITYVAL
header (1 word), after which appear the elements of the tuple.
The arity part of theARITYVAL
header is a 26-bit (on a 32-bit system) integer value containing the number of elements in the tuple.

I am newly learning Python, and I am trying to create a bfs algorithm that can take vertices of a weighted graph and return the bfs. Eventually, I will need to add the weighted edges to the vertices so that I can calculate the distance travelled, however I am able to get the bfs to work with my vertices alone. This is the code so far:
