Student Fit Problem

T is the number of total students
n is the number of teachers/classes
c is the number of students per class

c = T / n

for every value of n, I want to also compute r, or "the number of students you can add to T to get c to rise to the next whole number"

const CoolName = () => 'cool'
export { CoolName }

import { CoolName } from './file1a'
console.log(CoolName.name) // -> "CoolName"
