  assert remove_whitespace(['Hello  World  ', 'Hi  there', 'Good  Morning'])==['HelloWorld', 'Hithere', 'GoodMorning']
  assert remove_whitespace(['  Python  ', '  Coding  ', '  is   Fun  '])==['Python', 'Coding', 'isFun']
  assert remove_whitespace([''])==['']
  assert remove_whitespace([])==[]
output: def remove_whitespace(strings):
      return [''.join(s.split()) for s in strings]
