input: Write a function to convert a list of strings into a single camelCase string. The function should take a list of strings as input and return a new string where each string is capitalized and concatenated without spaces. 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(["camel", "case", "example"]) == "CamelCaseExample"
  assert convertToCamelCase([]) == ""
output: def convertToCamelCase(strings):
      if not strings:
          return ""
      return ''.join([word.capitalize() for word in strings])
