Total average is the average of all valid values:

discard = 2
array 0 = 800,1200,2100,4100,1300,700 // discard 800,1200 at start and 1300,700 at end
array 1 = 1000,1500,4500,5000,5800,2000,1500 // discard 1000,1500 at start and 2000,1500 at end

total avg = (2100 + 4100 + 4500 + 5000 + 5800) / 5

I have no idea what is happening in random tests and how to debug them.

As I understood it [0, 4] are X coordinates and [0, 0] are corresponding Ys.

Python

logistic_map(5,2,[0,4],[0,0])
#returns
#[[0,1,2,1,0],
#[1,2,3,2,1]]

AFAIK Manhattan distance is calculated |x2-x1| + |y2-y1|.

So at (0,3) with supplys at (0,0) and (4,0) I got:

|0-0| + |0-3| = 3

and

|4-0| + |0-3| = 7

But the answer is 1. Did I misunderstand something? TIA.

  [[64, 63, 3, 4, 5, 6, 58, 57], 
   [56, 55, 11, 12, 13, 14, 50, 49], 
   [17, 18, 46, 45, 44, 43, 23, 24], 
   [25, 26, 38, 37, 36, 35, 31, 32], 
   [33, 34, 30, 29, 28, 27, 39, 40], 
   [41, 42, 22, 21, 20, 19, 47, 48], 
   [16, 15, 51, 52, 53, 54, 10, 9], 
   [8, 7, 59, 60, 61, 62, 2, 1]] 
   
   should equal 
   
   [[64, 2, 3, 61, 60, 6, 7, 57], 
    [9, 55, 54, 12, 13, 51, 50, 16], 
    [17, 47, 46, 20, 21, 43, 42, 24], 
    [40, 26, 27, 37, 36, 30, 31, 33], 
    [32, 34, 35, 29, 28, 38, 39, 25], 
    [41, 23, 22, 44, 45, 19, 18, 48], 
    [49, 15, 14, 52, 53, 11, 10, 56], 
    [8, 58, 59, 5, 4, 62, 63, 1]]

AFAICT that is also a magic square. So why isn't it an acceptable answer?

Python,

Testing for: s=TyTYLX TtEheF xXm MOXruUK bNZU, n=3
'tyTYLXTtEheFXXMMOXruUKBNZu' should equal 'tytylXTteheFXxMMoxruuKBnzu'

As I understood it:

TyTYLX  => TyTYLX 
TtEheF  => TtEheF
xXm     => XXM
MOXruUK => MOXruUK
bNZU    => BNZU

TyTYLXTtEheFXXMMOXruUKBNZU => tyTYLXTtEheFXXMMOXruUKBNZu

I wanted to do this, but didn't think it would alow so many characters.

In Python, fixed tests

String: 798174707585847782767269738083867178
Size: 18
[68, 85] should equal [69, 86]

String: 937175789196798988958481879092738677708380947485827672
Size: 27
[69, 95] should equal [70, 96]

I don't understand why those answers are wrong.

Python, 4th sample test:

a = "c611d9bdd9de38b9eb" => "110001100001000111011001101111011101100111011110001110001011100111101011" 
b = "23a0745505d4d25494" => "1000111010000001110100010101010000010111010100110100100101010010010100"

If we cut from right:

a = "1100011000010001110110011011110111011001110111100011100010111001111010"
b = "1000111010000001110100010101010000010111010100110100100101010010010100"

a ^ b = "0100100010010000000010001110100111001110100011010111000111101011101110" =>
=> "1224023a73a35c7aee"

If we cut from the left:

a = "0001100001000111011001101111011101100111011110001110001011100111101011"
b = "1000111010000001110100010101010000010111010100110100100101010010010100"

a ^ b = "1001011011000110101101111010001101110000001010111010101110110101111111" =>
=> "25b1ade8dc0aeaed7f"

Expected answer:

 e5b1ade8dc0aeaed7f

first_dup('tweet') => 't'

First sample test:

first_dup('tweet'), 'e'

"If no word is found, the first character is deemed the longest "word", regardless of its validity".

Since there are no valid words that start with "e","w","g","s","a" - we add the first character.

So why in "goodluck" we don't add "o", "d", "u", "c", "k"?

I don't understand the first fixed test in java - we're looking for Charlotte Hornets. These are their games:

Miami Heat 104 Charlotte Hornets 94
Indiana Pacers 98 Charlotte Hornets 86
Detroit Pistons 94 Charlotte Hornets 99
Charlotte Hornets 94 Chicago Bulls 86
Miami Heat 104 Charlotte Hornets 94
Indiana Pacers 98 Charlotte Hornets 86
Detroit Pistons 94 Charlotte Hornets 99
Charlotte Hornets 94 Chicago Bulls 86
Miami Heat 104 Charlotte Hornets 94
Indiana Pacers 98 Charlotte Hornets 86
Detroit Pistons 94 Charlotte Hornets 99
Charlotte Hornets 94 Chicago Bulls 86

Total 12 games, but the expected answer is:

 expected:<Charlotte Hornets:W=[2;D=0;L=2;Scored=373;Conceded=382;Points=6]> 

Is there something I misunderstood about the question?

I don't understand if double space is a bug or a feature (Java);

Could someone explain this to me?
