Find complete batches

YOUR TASK

Make this happen

3 steps

  1. The remainder operator % reports what is left after division. A batch is complete when its quantity divides evenly by the batch size.

  2. Read the cases in lesson.test.lua, then choose Check solution to see what needs to change.

  3. Update subject.lua until every test passes. Keep the supplied tests unchanged.

Start with Check solution, then use the failures to guide your edits.

Read the starter and tests

subject.lua

exports.complete = function(quantity: number, size: number): boolean
  return false
end

lesson.test.lua

local t = require("test")
local subject = require("cococo.subject")

t.it("complete batch", function()
  local s = subject.load()
  t.expect(s.complete(12, 4)):eq(true)
end)

t.it("partial batch", function()
  local s = subject.load()
  t.expect(s.complete(13, 4)):eq(false)
end)

t.it("empty batch", function()
  local s = subject.load()
  t.expect(s.complete(0, 4)):eq(true)
end)
