given a number, find all the fangs of that number.
A pseudo-vampire number can have multiple of fangs. The output should be a cell containing all the pairs of possible fangs.
For example, 126 is a pseudo-vampire number whose fangs are - { '6' , '21' }
- 126 = 6*21
- 6 and 21 contains the digits of the original number.
