Have the function VowelSquare(strArr) take the strArr parameter being
passed which will be a 2D matrix of some arbitrary size filled with
letters from the alphabet, and determine if a 2x2 square composed
entirely of vowels exists in the matrix. For example: strArr is

When calling an API function, most of the times you either receive a success flag or an error message/object. (Some throw an exception). When the API does not throw exception do you generate application level exception or handle it with if/else structure?
My question is when your API either wha...
I'm fairly new to d3 and am wanting to create a visualization that will allow a user to check whether or not a device will be in range of a bluetooth speaker.
I was able to hack together most of what I want, but am not sure if I'm following d3 best practices. This will be eventually integrated ...
I have a need to update thousands of database records at a time. I am using a loop to generate the necessary PreparedStatement updates, but am hoping for a more efficient method.
Normally, I would try to use a batch operation, but since the number of fields I need to update for each record diffe...
I've written the resource below which acts as an API Proxy that leverages, at the moment, always the same file and basic authentication as part of the POST.
I am wondering how can I cache the request instead on rebuilding it on every call. I am not sure whether the content of the input.xml file ...
I'm currently working on an approval system right now using PHP (Codeigniter) and I have this method of getting all the request according to your department group and position depth.
The checking of the requests is based upon the user's position depth. 6 being the lowest and 1 being the highest....

I have the following piece of code in a for loop:
if (idx < d):
array_index = idx
ex_array[array_index] = foo()
else:
array_index = d - 1
np.roll(ex_array, -1)
ex_array[array_index]= foo()
It is an array that start getting shifted after (usually) 40 iterations. From that m...
This is my program implementation using DP. I don't know if my approach is correct or not. I would appreciate any feedback.
In a matrix given below, we have 8 square submatrices, (seven 1 X 1 square matrices), and one 2 x 2 square matrix whose values are all ones.

Recently I was being quite pedantic about code code I was reviewing. And I came across this line of code.
int retries = 0;
I liked the var keyword better and so did many others. Until one team member asked "What about uints?" We agreed that if we intended on using a uint we wound be explicit. B...
I have made some code in c#. I am currently developing a Gameserver so I have a function to update fields in the database. I also have a function to update the player-cash, but its like almost the same code. So my question is, do you guys have an idea to put this into one function?
