    Write a function that determines if a student's assigned practice problem number has the special property where it equals one less than double its reverse - a pattern used by our adaptive learning system to gauge pattern recognition skills and adjust subsequent problem difficulty. For example, if a student receives problem number 36, the system should verify if 36 is one less than twice its reverse (63), which in this case is true since 36 is one less than 126 (twice 63).
