#CCC21J3. Secret Instructions
Secret Instructions
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:
- If their sum is odd, then the direction to turn is left.
- If their sum is even and not zero, then the direction to turn is right.
- If their sum is zero, then the direction to turn is the same as the previous instruction.
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.
Input Specification
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 99999
.
Output Specification
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 right
or left
, followed by a single space, followed by the number of steps to be taken in that direction.
Sample Input
57234
00907
34100
99999
Output for Sample Input
right 234
right 907
left 100
Explanation of Output for Sample Input
The first instruction is 57234
which is decoded as right 234
because 5+7=12 which is even and 57
is followed by 234
.
The second instruction is 00907
which is decoded with the same direction as the previous instruction (right
) but with 907
steps.
The third instruction is 34100
which is decoded as left 100
because 3+4=7 which is odd and 34
is followed by 100
.
The last line contains 99999
which tells us these are the only three instructions.
