Professor Santos has decided to hide a secret formula for a new type of biofuel. She has, however, left a sequence of coded instructions for her assistant.
Each instruction is a sequence of five digits which represents a direction to turn and the number of steps to take.
The first two digits represent the direction to turn:
The remaining three digits represent the number of steps to take which will always be at least 100.
Your job is to decode the instructions so the assistant can use them to find the secret formula.
There will be at least two lines of input. Each line except the last line will contain exactly five digits representing an instruction. The first line will not begin with
00. The last line will contain
99999 and no other line will contain
There must be one line of output for each line of input except the last line of input. These output lines correspond to the input lines (in order). Each output line gives the decoding of the corresponding instruction: either
left, followed by a single space, followed by the number of steps to be taken in that direction.
57234 00907 34100 99999
right 234 right 907 left 100
The first instruction is
57234 which is decoded as
right 234 because 5 + 7 = 12 which is even and
57 is followed by
The second instruction is
00907 which is decoded with the same direction as the previous instruction (
right) but with
The third instruction is
34100 which is decoded as
left 100 because 3 + 4 = 7 which is odd and
34 is followed by
The last line contains
99999 which tells us these are the only three instructions.
