A word ladder puzzle begins with two words and to solve the puzzle one must find a chain of other words to link the two, in which two adjacent words differ by one letter.

The set is a data structure that can store values without any order and do not contain duplicate elements. The set is a computer implementation of a finite set. It contains finite natural number of elements. The subset is a set build from master set and has few elements. Example, Set S={1, 2, 3, 4, 5}, Subset = { {1, 2, 3}, {2, 3}, {1}}. The set can be implemented using linked lists, vectors and hash tables.
