what's the key difference? 

 

 

• map(int, input().split()):
  • Processes the input into two integers and unpacks them.
  • map(int, ...) converts each string in the list to an integer (e.g., [10, 20]).
  • The two integers are unpacked into variables A and B.
• (input(), split()):
  • Is invalid because split() is not called on a string, and unpacking into A, B doesn’t make sense here.
