Write a python code with user input defined.
You are developing a text editor that allows users to perform various operations on the text using the "CustomStack" class. The class supports the following operations:
insert(value): Inserts a string of characters at the current cursor position in the text.
delete(value): Deletes the last value characters from the text starting from the current cursor position.
get(value): Retrieves the character at index value from the text and displays it.
undo(): Reverts the last executed command on the text.
Each command is represented by a string in the following format:
1.Command 1: '1 value' - Inserts the string value at the current cursor position in the text.
2.Command 2: '2 value' - Deletes the last value characters from the text starting from the current cursor position.
3.Command 3: '3 value' - Retrieves the character at index value from the text and displays it.
4.Command 4: '4' - Reverts the last executed command on the text.
Consider a scenario where you have a text editor with a "CustomStack" class that implements the required operations. Assume the initial text is empty.
Important Note: Ensure that you save your solution before progressing to the next question and before submitting your answer.
1 abc,3 3,2 2,3 1
1 abc -> command and input text
3 3 -> command and index of the stack
1 zxy,3 3,2 2,1 def,3 2
make sure your code is completely correct and I will rate it definitely.
I want code to be copied type for myself.
