557. Reverse Words in a String III

Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.

Example 1:

Input: “Let’s take LeetCode contest”

Output: “s’teL ekat edoCteeL tsetnoc”

Note: In the string, each word is separated by single space and there will not be any extra space in the string.

嗯，这个和前三个字符串反转是同样的道理。

/**
* @param {string} s
* @return {string}
*/
var reverseWords = function(s) {
var d=s.split(" ");
for(var i=0;i<d.length;i++){
d[i]=d[i].split("").reverse().join("");
}
return d.join(" ");

};
