Problem

CodeChef recently revamped its practice page to make it easier for users to identify the next problems they should solve by introducing some new features:

  • Recent Contest Problems - contains only problems from the last 2 contests
  • Separate Un-Attempted, Attempted, and All tabs
  • Problem Difficulty Rating - the Recommended dropdown menu has various difficulty ranges so that you can attempt the problems most suited to your experience
  • Popular Topics and Tags

Our Chef is currently practicing on CodeChef and is a beginner. The count of ‘All Problems’ in the Beginner section is �. Our Chef has already ‘Attempted’ � problems among them. How many problems are yet ‘Un-attempted’?

Input Format

  • The first and only line of input contains two space-separated integers � and � — the count of 'All problems' in the Beginner's section and the count of Chef's 'Attempted' problems, respectively.

Output Format

Output a single integer in a single line — the number of problems that are yet 'Un-attempted'
