AWS_CDK is provides abstractions to write programmable cloud formation templates. We are using TypeScript.
But, I see that AWS CDK did not provide abstractions to separate state from logic. In the sense, below example from cdk documentation:

I came across a pretty simple question where the author explicitly states:
The function returns the correct output, and all known edge cases have been accounted for.
I took this at face value and started writing up a quick review. Examining the code further, it turned out to be broken. I we...

I have 2 data structures with me in JS. One is an array say of length N. Let's consider N = 4.
const arr = ['a', 'b', 'c', 'd'];
The second one is an object:
const obj = {
a: 0,
b: 2,
c: 3,
z: 5
};
I wrote a code in Javascript, to create a new object out of obj which should not cont...
There are exactly ten ways of selecting three from five, 12345:
123, 124, 125, 134, 135, 145, 234, 235, 245, and 345
In combinatorics, we use the notation, 5C3=10.
In general, nCr = n! / r! (n−r)!, where r≤n, n! = n × (n−1) × ... × 3 × 2 × 1, and 0! = 1.
It is not until n = 23, that a value e...

I've been fiddling around with some easy code challenges and there's one about determining if a triangle is equilateral, isosceles, or scalene.
I've come up with a working solution, but I feel this could be greatly improved and/or simplified.
The sides of a triangle come in a list e.g. [2, 2, 2...
I've got below implementation for my controller and show action which implements MiniMagick gem. I've just wondering is there any better way to write it down? If block in a separate, private method maybe?

I'm using flexbox to create a simple header, hero image with caption and footer.
As you can see from my snippet, the header is fixed and the hero image scrolls underneath.
Is there a way to achieve my layout without fixed or absolute positioning? I'm relatively new to flexbox and and haven't co...

this method definition for you to implement:

Am I right in thinking that this will automatically close a file?
def get_file():
with open("file.csv", "rb") as f:

If not, how do i write a function that returns a file object, whilst making sure that it closes the file after the receiver is done using it?

AskUser has been developed as a means by which to get a single keystroke in non-canonical mode without echo and return the ASCII value to calling procedure. Prompting should be intuitive enough that the user realizes input in the range of 0-9 or A-Z or any ASCII character from 32 to 127 for that...

At the moment I have this:

let result = 0;
var regex = /(\d+[a-z]+)/g;
match = regex.exec(str);
while (match != null)

var last_char = match_str[match_str.length-1];
if ( last_char == 'h' )

"This is {0} cool!", "freaking"
I've always wanted an easy and intuitive way to inject variables into a string. So after about 10 variations, I finally came up with this function.
