swaparray is not defined

The error message "swaparray is not defined" typically means that you are trying to use a variable or a function that has not been defined or declared in your code. Here are some possible reasons for this error:

1. Typo: You might have misspelled the name of the variable or function, causing the program to not recognize it.

2. Scope: The variable or function might not be defined in the scope where you are trying to use it. For example, if you define a variable inside a function, it will only be accessible within that function.

3. Missing import: If you are using a function from a module, you need to make sure that you have imported that module first.

To fix this error, you need to make sure that the variable or function is properly defined and declared in your code. If you are still having trouble, try checking your spelling and reviewing the scope and import statements in your code.
