In this blog post about breadth-first traversal, Gibbons talks about implementing BFT with "long zip with" function

I am trying to dynamically update a selectInput() value based on a dynamically updated selectInput() value. I can get the first value to update dynamically, but when I try and use those to update further values, I get an error:

I'm currently reading Algorithm Design with Haskell by Richard Bird & Jeremy Gibbons, the Saddleback search algorithm is given in chapter 4 after binary search, The problem given for motivation is :

given f:N x N -> N is strictly increasing in both arguments, and a value t find all the pairs (x,y) such that f(x,y)=t.

The first definition is given by search f t =[(x,y) | x ← [0..t],y ← [0..t],t == f(x,y)],which searches starting from the origin at the bottom-left corner to the top-right corner, (the indices are increasing from bottom to top and from left to right), then the book proceeds for improvements.

The second definition is given by search f t =[(x,y) | x ← [0..t], y ← [t,t −1..0],t == f(x, y)], The book quotes this definition with

"The first improvement is to start at the top-left rather than the bottom-left corner", then the book continues till it becomes Theta(m+n) for a matrix with dimensions n x m.

The final algorithm looks like this

I'm aware of the recent mimemagic issues, which I managed to resolve on one of my Rails projects by bundle updating to 0.3.7 - but for some reason, I can't resolve it on the project below.

I have a Rails 6 project which I'm setting up for the first time on a new laptop. My laptop doesn't have the correct Ruby setup, so I've added a Dockerfile to my project like so:-

Dockerfile

Instructions: Create a function expression named searchFirstNames. The searchFirstNames function should contain parameters named namesAr and nameQuery. Within the searchFirstNames function implement a .filter method on the array called namesAr and return an array of names where the first name matches the argument nameQuery.

Example: If names array contains the names "Anthony Jackson" and "Jaco Pastorious" and the namesQuery is "Anthony" then the result of calling the function searchFirstNames should be an array containing "Anthony Jackson"

Call the function searchFirstNames with the argument fullNames and nameQuery set to be "John" and store the resulting array into a variable named at your discretion.

My result: So, I called the function searchFirstNames with the arguments fullNames and "John" and I stored the resulting array into a variable called matchingFirstNames. Unfortunately, matchingFirstNames comes back as undefined when it should be an array containing "John Smith".

I have learned about SwiftUI, and am having difficulties to understand List in SwiftUI.

The List definition is below.

I am trying to pass a choice from a dropdown into my XSLT in order to filter results. It doesn't want to work properly though for whatever reason.

When I hard-code the appropriate value into the query it gives the desired result. Googling this issue every which way has also not yielded much help. I believe the problem may be in the way xsltProcessor.setParameter is parsing the data, not sending it through correctly to the XSLT.

I have two data frames:
