In this Upstart coding challenge, you are tasked with interleaving three input strings that are guaranteed to have the same length. The objective is to construct a new string by sequentially appending characters from each of the three original strings at corresponding positions. Specifically, for every index, you should take the character from the first string, then the second, and finally the third, repeating this pattern across the entire length. This problem evaluates your fundamental string manipulation skills and ability to iterate through multiple sequences simultaneously. The full problem and model solution require a subscription.
