Задача 2. Change List дава Runtime error на единия от тестовете

Здравейте,

Не можах да открия къде се дъни.

Моля помогнете да намеря грешката.

Приятен ден!

Задачата е :

Write a program, which reads a list of integers from the console and receives commands, which manipulate the list. Your program may receive the following commands:

Delete {element} – delete all elements in the array, which are equal to the given element
Insert {element} {position} – insert element and the given position

You should stop the program when you receive the command "end". Print all numbers in the array separated with single whitespace.

Examples

Input

Output

1 2 3 4 5 5 5 6

Delete 5

Insert 10 1

Delete 5

end

1 10 2 3 4 6

20 12 4 319 21 31234 2 41 23 4

Insert 50 2

Insert 50 5

Delete 4

end

20 12 50 319 50 21 31234 2 41 23

Решението ми е:
