Digit Processing

Digit Processing

This problem consists of processing multiple data sets. For each data set, you will be given 5 digit characters. Let the digits be denoted as \(d_1, d_2, d_3, d_4, d_5\).

For each data set, perform the following:

  • Compute \(S = d_1 + d_2\) (treating \(d_1, d_2\) as their integer values).
  • If \(S\) is odd, then output left.
  • If \(S\) is a nonzero even number, then output right.
  • If \(S = 0\), then output the same result (left or right) as produced by the previous data set. For the first data set, if \(S = 0\), assume the result is left.

After determining the appropriate word, output a single space followed by the concatenation of the last three digit characters \(d_3, d_4, d_5\).

Note: There is no count given for the number of data sets; you should process until the end of the input.

inputFormat

The input consists of multiple lines. Each line contains exactly 5 digit characters (without spaces) representing a data set.

outputFormat

For each input data set, output a line containing the result based on the above rules. Each line should have the determined word (left or right), then a space, then the last three digits from the input data set.
