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.
桑托斯教授决定隐藏一种新型生物燃料的秘密配方。然而，她为她的助手留下了一系列编码指令。每条指令是一个由五位数字组成的序列，代表要转的方向和要走的步数。
前两位数字代表转向的方向：
如果它们的和是奇数，那么转向方向是左。
如果它们的和是偶数且不为零，则转向方向是右。
如果它们的和为零，那么转向方向与上一条指令相同。
剩下的三位数字代表要走的步数，这个数字总是至少100。
你的工作是解码指令，以便助手可以使用它们找到秘密配方。

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.

除最后一行外，每一行都将包含五位数字，代表一条指令。第一行不会以00开头。最后一行将包含99999，而其他行不会包含99999。

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.

除了最后一行输入外，每一行输入必须有一行输出。这些输出行对应于输入行（按顺序）。每个输出行给出相应指令的解码：右转或左转，后面跟着一个空格，然后是要在那个方向上走的步数。
