input: Write a function that takes a list of strings, converts each string to camelCase by capitalizing the first letter, and returns a new list with the converted strings. If the input list is empty, the function should return an empty list.
  assert convertToCamelCase(["this", "is", "an", "example"]) == "ThisIsAnExample"
  assert convertToCamelCase(["hello", "world"]) == "HelloWorld"
  assert convertToCamelCase(["a", "b", "c"]) == "ABC"
  assert convertToCamelCase(["", "", ""]) == ""
  assert convertToCamelCase([]) == []
output: def convertToCamelCase(strings):
      if not strings:
          return []
      return ''.join([s.capitalize() for s in strings])
