Find numbers which are palindrome in both their decimal and octal Representations

Objec­tive: Given a range of inte­gers, find all the num­bers which are palin­drome when they are rep­re­sented in Dec­i­mal Value( base 10) and in Octal value(base 8).

Exam­ple :

Number : 373 (Decimal) and digits are palindrome.

Convert it into Octal which is 565 and that's also palindrome.


Solu­tion is quite sim­ple. Tra­verse through all the num­bers in the given range and check if it palin­drome, if yes, con­vert it into Octal and check for palin­drome again.
