Здравейте!

Опитах се да реша задачата Array Manipulator от Arrays Advanced Exercise , но в judge получавам 63/100 - https://pastebin.com/yiTfCKdW

Ще се радвам да ми кажете къде греша.

Благодаря!

Ето го и условието:

8. *Array Manipulator

Write a function that receives an array of integers and an array of string commands and executes them over the array. The commands are as follows:

• add <index> <element> – adds element at the specified index (elements right from this position inclusively are shifted to the right).
• addMany <index><element 1> <element 2> … <element n> – adds a set of elements at the specified index.
• contains <element> – prints the index of the first occurrence of the specified element (if exists) in the array or -1 if the element is not found.
• remove <index> – removes the element at the specified index.
• shift <positions> – shifts every element of the array the number of positions to the left (with rotation).
  • For example, [1, 2, 3, 4, 5] -> shift 2 -> [3, 4, 5, 1, 2]
• sumPairs – sums the elements in the array by pairs (first + second, third + fourth, …).
  • For example, [1, 2, 4, 5, 6, 7, 8] -> [3, 9, 13, 8].
• print – stop receiving more commands and print the last state of the array in the following format:

     `[ {element1}, {element2}, …elementN} ]`

  Note: The elements in the array must be joined by comma and space (, ).
