The Lucky House

Question

There's a minigame in Super Mario 3D World known as the Lucky House. It consists of a slot machine with 4 blocks.

Each block may be one of 5 different icons (Flower, Leaf, Bell, Cherry or Boomerang) and the goal of the player is to get as many identical icons as possible (see a video).

The player is rewarded with coins, which in turn may be converted into extra lives. Your task is to compute the number of extra lives won.

Depending on the number of icons that match, the amount of coins rewarded are as follows:

• No matches - 10 coins
• One pair - 100 coins
• Two pairs - 200 coins
• Three-of-a-kind - 300 coins
• Four-of-a-kind - 777 coins

You win one extra life (1UP) every 100 coins. Therefore, you're guaranteed to win exactly 1UP with one pair, 2UP with two pairs and 3UP with 3-of-a-kind. However, the number of lives won with no matches or 4-of-a-kind depends on your initial coin stock.

Input

You're given the initial coin stock \$0 \le c < 100\$ and a list of four values \$[v_1,v_2,v_3,v_4]\$ representing the final icons on the slot machine.

Output

The number of extra lives won: \$0\$, \$1\$, \$2\$, \$3\$, \$7\$ or \$8\$.

Rules

• You may take the icons in any reasonable format: e.g. as a list, as a string or as 4 distinct parameters.
• Each icon may be represented by either a single-digit integer or a single character. Please specify the set of icons used in your answer. (But you don't have to explain how they're mapped to Flower, Leaf, Bell, etc., because it doesn't matter at all.)
• You are not allowed to remap the output values.
• This is 🎰code-golf🎰.

Test cases

In the following examples, we use a list of integers in \$[1..5]\$ to represent the icons.

-------------------------------------------------------------------------
  0    [1,4,2,5]    0      no matches  ->  0 +  10 =  10 coins -> nothing
 95    [3,1,2,4]    1      no matches  -> 95 +  10 = 105 coins -> 1UP
 25    [2,3,4,3]    1      one pair    -> 25 + 100 = 125 coins -> 1UP
 25    [4,5,5,4]    2      two pairs   -> 25 + 200 = 225 coins -> 2UP
  0    [2,5,2,2]    3      3-of-a-kind ->  0 + 300 = 300 coins -> 3UP

 23    [3,3,3,3]    8      4-of-a-kind -> 23 + 777 = 800 coins -> 8UP
 99    [3,3,3,3]    8      4-of-a-kind -> 99 + 777 = 876 coins -> 8UP

            DONE:

Input starting coin count in DX, SI pointing to start of "icon" bytes (which can be '1'-'5', or any byte value). Output the number of 1UP's in BX.

Explanation:

The input of four bytes is iterated and compared to the remaining bytes to the right, counting the number of matches. The scores for each type of match are awarded and add up to the total. Since a four-of-a-kind is also three-of-a-kind and also a one-pair, the value of each score type can be decomposed as follows:

• 3 matches = 4 1UP's + 77 coins
• 2 matches = 2 1UP's
• 1 match = 1 1UP

Examples:

[2, 2, 2, 2] (four-of-a-kind) = 7 1UP's + 77 coins

2 [2, 2, 2] = 3 matches = 4 1UP's + 77 coins
   2 [2, 2] = 2 matches = 2 1UP's
      2 [2] = 1 match   = 1 1UP

[2, 5, 2, 2] (three-of-a-kind) = 3 1UP's

2 [5, 2, 2] = 2 matches = 2 1UP's
   5 [2, 2] = 0 matches
      2 [2] = 1 match   = 1 1UP

[4, 5, 5, 4] (two pair) = 2 1UP's

4 [5, 5, 4] = 1 match   = 1 1UP
   5 [5, 4] = 1 match   = 1 1UP
      5 [4] = 0 matches

[2, 3, 4, 3] (one pair) = 1 1UP

2 [3, 4, 3] = 0 matches
   3 [4, 3] = 1 match   = 1 1UP
      4 [3] = 0 matches

If number of earned 1UP's is 0 at the end, 10 coins are awarded. If total coins are greater than 100, an additional 1UP is awarded.

I had the same idea as GammaFunction to use sum(map(l.count,l)) as a "fingerprint". But, instead of using an arithmetic formula on the result, I use a lookup table, first squishing the value to 0 through 4 using a mod chain %14%5. Dividing all the point values by 100 saved a few bytes.

Answer 12

Perl 5 -pF, 46 bytes

map$q+=$$_++,@F;$_=0|<>/100+($q>5?7.77:$q||.1)

Try it online!

First of input is the spin result, using any 5 unique ASCII letters, except q (I suggest abcde). The second line of input is the current coin count.

How?

-F     # CLI option splits the input into individual characters in @F
map
   $q+=   # $q holds the result of the calculation here
          # possible values are 0,1,2,3,6
   $$_    # This interprets $_ as a variable reference, thus if $_ is 'a', this variable is $a
   ++     # increment after adding it to $q
,@F;      # iterate over the elements of @F
$_=0|     # force the result to be an integer
   <>/100 # divide the current coin count by 100
   +($q>5?7.77  # if $q is over 5, then there must have been 4 of a kind
   :$q||.1)     # otherwise, use $q, unless it is 0, then use .1
-p        # CLI option implicitly outputs $_

All of the numbers involved are divided by 100, so the program is counting the number of lives (including partial ones) currently earned. The trick to this solution is in the map. If the possible entries are abcde, then each of $a, $b, $c, $d, and $e hold the count of the number of times this character had previously been seen. That gets added to a running total ($q) each time a character is seen. The running total is bumped up if there is a four of a kind (effectively a 177 coin bonus).

Try it online!

I figured there had to be at least one JavaScript answer to an Arnauld challenge!

The concept here is mainly to use the number of distinct elements as a lookup key.

• 1 unique => 4 of a kind
• 2 unique => 2 pair or 3 of a kind
• 3 unique => 1 pair
• 4 unique => no matches

In order to distinguish between 2 pair and 3 of a kind, the input array is sorted and the middle 2 elements are compared.

Run and debug it

This program uses any arbitrary set of 5 integers for icons.

Procedure:

1. Add up the number of occurrences of each element.
2. Divide by 2 and then mod 7.
3. The result is a number from 1..5. Use this to look up the coin prize in a fixed array.
4. Add to the initial coin count.
5. Divide by 100.

Here's the output from an experimental stack state visualizer I've been working on for the next release of stax. This is an unpacked version of the same code with the stack state added to comments.

Try it online! Link includes test cases. Takes input as 4 printable ASCII non-digits followed by the initial number of coins in digits. Explanation:

(\D)\1{3}
777¶

Four-of-a-kind scores 777.

w`(\D).*\1
100¶

Each pair scores 100. The w takes all pairs into consideration, so that they can be interleaved, plus three-of-a-kind can be decomposed into three pairs, thus automagically scoring 300.

\D{4}
10¶

If there were no matches then you still win!

\d+\D*

-1 by x+=(..!=..) -5 by returning via assignment, -4 thanks to Jonathan Allan by replacing != with <, which saves bytes elsewhere, -1 by rearranging the ternary.

From @ceilingcat: -2 by declaring i and x outside the function, -1 by setting x=i and decrementing x instead.

i,x;f(c,a)int*a;{for(i=x=16;i--;)x-=a[i/4]>=a[i%4];c=x?x-6?6-x:c>89:7+(c>22);}

-2 bytes thanks to @Grimy.

Takes the list of icons as first input (being [1,2,3,4,5]), and the amount of coins as second input.

Try it online or verify all test cases. (The test suite uses T‚à+ instead of TMI+, which is an equal bytes alternative.)

Explanation:

D                   # Duplicate the first (implicit) input-list
 ¢                  # Count the amount of occurrences in itself
  <                 # Decrease each count by 1
   O                # Sum these
    R               # Reverse it
     ;              # Halve it
      т*            # Multiply by 100
        777         # Push 777
           T        # Push 10
            )       # Wrap all three values into a list
             Åm     # Get the median of these three values
               +    # Add the second (implicit) input to it
                т÷  # And integer-divide it by 100
                    # (after which the result is output implicitly)

≔⊘ΣＥη№ηιηＩ⌊⁺∕θ¹⁰⁰∨⁻η∕²∨›⁸η⁹∕¹χ

Try it online! Link is to verbose version of code. Takes input as the number of coins and an array of any Python comparable values as icons. Explanation:

≔⊘ΣＥη№ηιη

Shamelessly steal @GammaFunction's trick of computing half the sum of counts.

⁻η∕²∨›⁸η⁹

Subtract 2 from the sum, thus resulting in the values 0, 1, 2, 3 appropriately, but for 4-of-a-kind, divide the 2 by 9 first, resulting in 7.777....

∨...∕¹χ

But if the result is 0, then there were no matches, so replace it with 0.1 instead. (Using a literal doesn't help me here because I would need a separator.)

Ｉ⌊⁺∕θ¹⁰⁰...

Divide the initial coins by 100 and add on the winnings, then floor the result and cast to string for implicit output.

Try it online!

A big ol' PowerShell-flavored ternary operation built upon grouping and sorting the counts of the input list. The sort is needed because we leverage the fact that the grouped list gets shorter the more repeats there are. In fact, here's all the possible values:

(1,1,1,1)
(1,1,2)
(2,2)
(1,3)
(4)

Truncating to an int is still expensive.

8051 Assembly (compiles to 158 bytes)

This is a VEEEEEEEEEERRY naive approch, this is yet untested and ungolfed but im pretty confident that works. Things to consider are:

1) the 8051 is an accumulator machine ie. it needs mov instructions that other architectures may not need at all.

2) the 8051 is an 8bit machine therefor there has to be done some trickery for the numbers >255 which makes for more code and is therefor a disadvantage of the platform over the others.
