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.
