- Consider a list (list = []). You can perform the following commands:
- insert i e: Insert integer e at position i.
- print: Print the list.
- remove e: Delete the first occurrence of integer e.
- append e: Insert integer e at the end of the list.
- sort: Sort the list.
- pop: Pop the last element from the list.
- reverse: Reverse the list.

Initialize your list and read in the value of n followed by n lines of commands where each command will be of the 7 types listed above. Iterate through each command in order and perform the corresponding operation on your list.

- Example
- N = 4
- append 1
- append 2
- insert 3 1
- print
- append 1: Append 1 to the list, arr = [1].
- append 2: Append 2 to the list, arr = [1,2].
- insert 3 1: Insert 3 at index 1, arr = [1,3,2].
- print : Print the array.

- Output:
1

[1, 3, 2]

- Input Format
- The first line contains an integer, n, denoting the number of commands.
- Each line i of the n subsequent lines contains one of the commands described above.

- Constraints
- The elements added to the list must be integers.

- Output Format
- For each command of type print, print the list on a new line.
