[PHP Basics - Exercises] - 04. Array Indexes

Задача: [PHP Basics - Exercises] - 04. Array Indexes
В Judge: https://judge.softuni.bg/Contests/Practice/Index/240#3
Моят код: http://pastebin.com/YQpFxZxb
Някой би ли могъл да ми каже защо Judge-a ми дава 100 точки, а при мен кода минава с втория тест (ТЕСТ 2):

А с първия тест:
0 – 5
1 – 6
2 - 7
дава странни стойности и съответно грешки, като например (... '0 – 5' (length=7) ):
Len(KeyValuePairs) = 3

 ' - ' (length=3)

 3


array (size=3)
  0 =>  '0 – 5' (length=7)
  1 =>  '1 – 6' (length=7)
  2 =>  '2 - 7' (length=5)

FOR:
0 – 5
