Array Manipulator 81/100
Може би правя грешка в някоя от последните 2 манипулации, но не откривам нищо.
Условие:
Write a function that receives an array of integers and 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.

[1, 2, 4, 5, 6, 7], ['add 1 8', 'contains 1', 'contains 3', 'print'] |
0 -1 [ 1, 8, 2, 4, 5, 6, 7 ] |
[1, 2, 3, 4, 5], ['addMany 5 9 8 7 6 5', 'contains 15', 'remove 3', 'shift 1', 'print'] |
-1 [ 2, 3, 5, 9, 8, 7, 6, 5, 1 ] |
Благодаря, от шифт манипулацията идва проблемът.
