题目描述

You have been given a string s, which is supposed to be a sentence. However, someone forgot to put spaces between the different words, and for some reason they capitalized the first letter of every word. Return the sentence after making the following amendments:

• Put a single space between the words.
• Convert the uppercase letters to lowercase.

Example

• For s = "CodefightsIsAwesome", the output should be
  amendTheSentence(s) = "codefights is awesome";
• For s = "Hello", the output should be
  amendTheSentence(s) = "hello".

Input/Output

• [execution time limit] 4 seconds (js)

• [input] string s

  A string containing uppercase and lowercase English letters.

  Guaranteed constraints:
  3 ≤ s.length ≤ 100.

• [output] string

  The amended sentence.
