The “Sudoku” below has 16 clues and two solutions. However the two solutions appear to only swap around the 8s and 9s. Since there are no 8s or 9s in the original puzzle does this mean the solution is unique?
It is believed that there is no Sudoku with 16 clues i.e. with a unique solution. It was mathematically proven in 2012 by Gary McGuire and his team that 17 is the minimum number of clues possible for a valid Sudoku puzzle to have a unique solution; puzzles with 16 or fewer clues cannot have only one solution.

The gift of giving …?
The author of “The Gift of the Magi” is O. Henry, a pseudonym for William Sydney Porter.
“The Gift of the Magi” is a poignant short story about a young couple, Jim and Della, who are deeply in love but financially struggling. With Christmas approaching and limited money, each decides to sacrifice their most prized possession to buy a meaningful gift for the other. Della sells her beautiful long hair to buy a platinum chain for Jim’s watch, while Jim sells his grandfather’s watch to buy a set of combs for Della’s hair. In the end, their love and sacrifice underscore the true spirit of giving during the holiday season.
