Reverse-Than-Add (196) Algorithm Demo

① This example demonstrates the iterative process of the reverse‑then‑add (196) algorithm, showing how any starting natural number is repeatedly reversed and added until a palindrome appears or the sequence falls into a suspected Lychrel trajectory. ② Core mathematical concepts include sequence iteration, palindrome detection, limit behavior, and the unsolved Lychrel conjecture. ③ Construction highlights: Sequence creates the iteration list; Length, ToBase, Mod, Div handle digit manipulation; Zip and Append build a text table; TableText displays the history; Textfield and InputBox provide interactive input. ④ Suitable for high‑school elective math, undergraduate discrete mathematics or introductory algorithms courses, and as a visual aid for mathematical modeling and computational thinking.
