rake 1:7 total confusion

The solution takes value of current_char to the string indexes from [0..n] then puts the value of the current_char if current_char is "r". So how does it ends up with the correct answer. And also what does setting the value of add_next to 'false' accomplishes. Removing it gives an error, setting it to true comes up with an additional '0' th index character. I am clueless and now kind of bashing my head for 3 hours straight. Can you please elaborate a little, that would be great. I am just a new seedling in the world of coding.

Okkay, I think I have just figured one part of it out. I don't know why it took me so long. You are just making the current_char to false so that the first iteration will not give away anything undesirable right.
But I still don't get why are you feeding the same value of 'r' to the to_return string. Please help.

Sorry but the way that I figured isn't making any sense anymore. I am in the dark again.

guys over at stackoverflow resolved it for me. Great way but a little too complicated!!

I'm going to reopen this, I don't have time to look at it right now, but any time you get the brand-new user's perspective is valuable, and worth taking into consideration for anyone who comes after them.
