sorry i missed your doubt

your mistakes

  1. you have to clear the vector after each testcases
    otherwise the new values will mix with old one
  2. the way of taking input is wrong
    it will not store the vector of pairs
    try to print the vector for more details

i have fixed all the errors

Modified Code
