Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Is a solution better than O(n^2) even possible?
how does one calculate the sol has O(n^2) ?
Each word needs to be reversed in place - you are reversing the entire string.
For example "This is an example!" should return "sihT si na !elpmaxe"
OK.. I have used three variations of the some code and I am getting errors. What in the world that I am doing wrong.
function reverseWords(s) {
var o = '';
for (var i = s.length - 1; i >= 0; i--)
o += s[i];
return o;
}
reverseWords("This is an example");
