Palindromes are numbers that read the same forwards as backwards. Like 12321.
Given a number base B (2 <= B <= 20), calculate all the number N( N no large than 300) such that N^2 is palindromic when expressed in base B.
Pay attention, 'A', 'B', and so on represent the digits 10, 11, and so on.
Print both the number and its square in base B.
A single line with B.
Lines with two integers represented in base B. The first integer is the number whose square is palindromic; the second integer is the square itself.
