input: Write a function to convert a list of strings to camelCase and return a new list with the converted strings. The function should ensure that each word in the list is capitalized except for the first word, which should be in lowercase. Return the result as a single concatenated string in camelCase format.
  
  assert convertToCamelCase(["this", "is", "an", "example"]) == "thisIsAnExample"
  assert convertToCamelCase(["hello", "world"]) == "helloWorld"
  assert convertToCamelCase(["first", "name"]) == "firstName"
  assert convertToCamelCase(["long", "term", "gain"]) == "longTermGain"
  assert convertToCamelCase(["single"]) == "single"
output: def convertToCamelCase(strings):
      if not strings:
          return ""
      camel_case = strings[0].lower()
      for word in strings[1:]:
          camel_case += word.capitalize()
      return camel_case
