I wrote a solution to first-unique-character-in-a-string:
Given a string, find the first non-repeating character in it and return it's index. If it doesn't exist, return -1.
If there is better way for me to build the dictionary seems? and find the first key when value is 1 and index is lowe...

This the code i wrote
k = 20
p = 20
for i in range(10):
for j in range(k):
print(end = ' ')
k = k - 1
print("#",end = '')
for t in range(p):
print(end = ' ')
p = p + 1

I am new to C# and going through Delegates and I am having trouble understanding
Why are Delegates declared as an abstract class?

I created the below comparer to allow me to use a generic dictionary as a key to another generic dictionary.
My GetHashCode implementation creates a hash based on all keys and their values; but I suspect its distribution could be improved?
Also my Equals method returns true only if the two argu...

I have a code for dynamically generating a Torus Segment depending on an angle (which I basically took from ProceduralPrimitives and made some changes to use the input angle instead of creating a complete torus):

I was curious about image manipulation and I was wondering how it was working, so I made some little functions wich are modifying the pictures passed in parameter.
The graphics results are not too bad, and the execution time is quite correct (even if i thinks it can clearly be improved).
So (beca...

I need to update a table in SQL with variable column name and variable value to that but when I tried it show this error.
We are launching some editor improvements today. These improvements are required as a part of our responsive design efforts, but we think they are generally useful in any case. So we are making them available on all sites.
So, what's being improved?

Basically, I'm trying to handle different fields in form i.e. input field and select tag. I wrote two different methods for that and I think that is too much of a code.
For <input> tag
handleChange = e => {
this.setState({ [e.target.name]: e.target.value });
};
For <select> tag

From a sorted vector of indices (toRemove), I would like to remove from another vector (v) the elements at these indices.
An easy way to do it would be to start with the last element of toRemove and remove them sequentially. However, that would require copying elements at the end of the vector s...

Your program expects the user to refer to completed or incomplete tasks by a numeric index. However, the Markdown file contains an unnumbered bulleted list, which forces the user to count the items manually (starting from 0). That design is inhumane. I suggest that you change the Markdown to u...
I have a method dataparse which takes an input of two files, each containing data formatted as follows: 12:13:08.078067 IP 172.16.114.148.ftp > 194.27.251.21.1303: Flags [P.] And stores it into a List<String>—in the format of list.get(0) = 172.16.114.148 and list.get(1) = 194.27.251.21—which is a...
We have a teams database with a relationship to listings. This API call allows them to filter the listings down into categories represented by each individual if statement. This is the only way I would think of doing it besides a switch statement.
