Sequinary Numerals

A sequinary numeral is a sequence of digits:

dndn-2...d1d0

where dn is 1 or 2 and the others are 0, 1, or 2.

It represents the rational number:

d0 + d1 * (3/2) + d2 * (3/2)2 + ... + dn * (3/2)n

Write a program which takes a sequinary numeral as input and returns the number it represents as a proper fraction.

The single line of input contains a sequinary numeral of no more than 32 digits.

Output consists of a single line.

If the result is an integer, the output is the decimal integer. Otherwise, the output is N a single space and K/M where N, K and M are decimal integers where K < M and K/M is in lowest terms (GCD(K, M) = 1).
