69c5f3d787b1725d5f00c8b9	Challenge 255: Earth Day Cleanup Crew	29	challenge-255

--description--

Today is Earth Day. Given an array of items you cleaned up, return your total cleanup score based on the rules below.

Given items will be one of:

Item	Base Value
"bottle"	10
"can"	6
"bag"	8
"tire"	35
"straw"	4
"cardboard"	3
"newspaper"	3
"shoe"	12
"electronics"	25
"battery"	18
"mattress"	38

A Rare item is represented as ["rare", value]. For example, ["rare", 80]. Rare items do not get a streak bonus.

• Streak bonus: If the same item appears consecutively, it gets increasing bonus points.

  • First consecutive occurrence: base value
  • Second: base value + 1
  • Third: base value + 2
  • etc.

• Fifth Item Multiplier: Every fifth item collected gets a multiplier.

  • Fifth item: *2
  • Tenth item: *3
  • etc.

• Apply the multiplier after calculating any bonuses.

get_cleanup_score(["bottle", "straw", "shoe", "battery"]) should return 44.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_cleanup_score(["bottle", "straw", "shoe", "battery"]), 44)`)
}})

get_cleanup_score(["electronics", "straw", "newspaper", "bottle", "bag"]) should return 58.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_cleanup_score(["electronics", "straw", "newspaper", "bottle", "bag"]), 58)`)
}})

get_cleanup_score(["shoe", "can", "can", "can", "bottle", "bottle", "straw", "straw", "straw"]) should return 79.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_cleanup_score(["shoe", "can", "can", "can", "bottle", "bottle", "straw", "straw", "straw"]), 79)`)
}})

get_cleanup_score(["mattress", ["rare", 80], "tire", "tire", "tire", ["rare", 95]]) should return 358.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_cleanup_score(["mattress", ["rare", 80], "tire", "tire", "tire", ["rare", 95]]), 358)`)
}})

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_cleanup_score(["bottle", "can", "can", "shoe", "shoe", ["rare", 56], "bottle", "bottle", "can", "can", "electronics", "bottle", ["rare", 48], "bottle", "can", "can", "can", "can", "can", "can", "can"]), 383)`)
