Env

Python: 3.11.0
TypeScript: 4.9.3
- Node.js: 18.12.1

Cheatsheet

Python
- Use sys.stdin (over input())
  - Read one line: sys.stdin.readline()
  - Iterate lines: for line in sys.stdin
    - or for line in open(0)
TypeScript
- ~~Deno offers their own stdin (and stdout) API: Deno.stdin.read~~
- Node offers two method for stdin.

Example Snippets

// Deno
const buffer = new Uint8Array(65_536)
const bytesLength = await Deno.stdin.read(buffer) as number
const input = new TextDecoder().decode(buffer.subarray(0, bytesLength))

// Node
// - readFileSync
import { readFileSync } from 'fs'
const input = readFileSync(0, 'utf-8')

// - readline
import { stdin } from 'node:process'
import * as readline from 'node:readline'

const rl = readline.createInterface({ input: stdin })

rl.on('line', (line) => {
  // Handle line
})
// or
for await (const line of rl) {
  // Handle line
}

Elixir
- IO.read(:stdio, :eof) does not work for some reason. It just stuck after getting EOF.
  - Walkaround: use File.read!("./input.txt") instead.
- rem/2 is different to Integer.mod/2 and can return a negative.
