sml | SML : C++14 State Machine Library

The below image is already close to the solution i am looking for (see my codepen). The only thing that is missing is a padding / gap between the outline border of or and the border of the

• What approach would you take if you had to create something that looks like the image above?
• How can i achieve that the dotted lines have some gap between the border of the td (/ tr) and the outline of either tr or tbody or table?

You can take a look at the code on codepen. My CSS approach is this

It's not that I don't understand how to find the integer square root of a number. I know several ways of finding them using Python and C++.

It's just that this algorithm is really messing with my brain. And having to write it in SML is another headache.

Please help me in understanding this algorithm. Do note that this should be using recursion:

The integer square root of 𝑛 is the integer 𝑘 such that 𝑘²≤𝑛<(𝑘+1)². The integer square root can be computed using the following inductive process:

1. Compute the integer square root 𝑖 of 𝑚 = 𝑛 div 4 recursively. We then have that 𝑖²≤𝑚<(𝑖+1)².
2. Since 𝑚 and 𝑖 are integers, we have that (𝑚+1)≤(𝑖+1)². We thus have (2𝑖)²≤4𝑚≤𝑛<4𝑚+4≤(2𝑖+2)².
3. Hence we have that the integer square root of 𝑛 is either 2𝑖 or 2𝑖+1.

Write a recursive ML program corresponding to the above algorithm.

I am new to SML and am trying to implement a BST. I have figured out how to parse through the tree, but am struggling with creating an insert function. I want the function to be: insert(bst, key, value) of type BST * int * int -> BST where it inserts a key-value pair into a given tree and returns the resulting tree. I am struggling in the creation of this though, because I get a bit confused on making sure the function is of the right type.

Here is my code so far, I have included an example tree as well

I am trying to compile from source and experiment with the examples in boost::sml. The visitor example in particular will not compile, so my application with sml is missing a straightforward way to just status which states its state machines are in.

I am running on a machine with the following statuses when doing the initial cmake setup:

The SML/NJ code below results in a binding not exhaustive warning for "val Grove(whatTree) = glen". The F# equivalent code produces no warning. Why?

I am new to SML. I am trying to create a function that outputs a list of all prime numbers which are smaller than or equal to a given integer n > 2 using the Sieve of Eratosthenes. I am running into a problem however where the output is only showing as [1]. I would like to be able to have an input such as 5 and get [1,3,5] as a result.

This is my code so far, I am very new so I know it is most likely not written correctly.

I have the following HTML which represents 2 of about 20+ reviews I have scraped. I didn't include the rest here because of space, but you can imagine that these blocks keep repeating.

I need to retrieve "sml-rank-stars sml-str40 star" (as seen in the second line here) from each review.

I've got this

In the following code:
