127. Numbers Palindrome in Both Decimal and Octal

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.


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