input: Write a function to convert a list of strings to camelCase and return a new list with the converted strings. The function should take a list of strings as input and return a concatenated string where each word in the list starts with an uppercase letter and there are no spaces between words. If the input list is empty, the function should return an empty string.
  
  assert convertToCamelCase(["this", "is", "an", "example"]) == "ThisIsAnExample"
  assert convertToCamelCase(["hello", "world"]) == "HelloWorld"
  assert convertToCamelCase(["a", "simple", "test"]) == "ASimpleTest"
  assert convertToCamelCase([]) == ""
output: def convertToCamelCase(strings):
      if not strings:
          return ""
      return "".join(word.capitalize() for word in strings)
