bborgesr / shiny-reactive-R6-object.R
Created August 1, 2017 21:22
Uses the reactiveTrigger() construct in an R6 object class in order to make it useful in reactive settings, like a Shiny app (MWE included)
library(shiny)
reactiveTrigger <- function() {
counter <- reactiveVal( 0)
list(
depend = function() {
counter()
invisible()
},
trigger = function() {

bborgesr / shiny-insertUI-removable.R
Last active June 7, 2023 12:07
Uses Shiny's insertUI to create elements (in this example, datatables) at the user's discretion; each of these comes with a button that will remove it from the app (using removeUI).
library(shiny)
ui <- fluidPage(
textInput("divID", "Enter an ID for the custom area:", ""),
helpText("Leave the text input blank for automatically unique IDs."),
actionButton("isrt", "Add a datatable"),
tags$div(id = "placeholder")
)
server <- function(input, output, session) {
rv <- reactiveValues()

Last active March 14, 2019 15:35
[Make a CMS card's id unique] Reusing existing code, and keeping in mind that it's preferrable to destructure the object rather than mutate the id in place. #cms
try {
const card = buildCard(
card,
data,
filtersAndFormatters,
Object.assign({}, settingsAndOptions, { cardIndex })
);
return {...card, id: `${card.id}:${cardIndex}`};
}

Grokking the coding interview equivalent leetcode problems

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window
