Bet smart 足彩必胜之道。

Richie听爸爸说，买足彩买国足输就完事了！于是他拿着爸爸给他的零花钱想去买彩票。可是，他发现不同的博彩公司对同一场比赛开出的赔率都不太一样。

Richie想问问你，请问是否有一种策略可以保证不管国足胜平负，他都一定赢钱？

To Bet or Not To Bet
DescriptionnnAlexander Charles McMillan loves to gamble, and during his last trip to the casino he ran across a new game. It is played on a linear sequence of squares as shown below. n![](http://poj.org/images/1644_1.jpg)nnA chip is initially placed on the Start square. The player then tries to move the chip to the End square through a series of turns, at which point the game ends. In each turn a coin is fl nipped: if the coin is heads the chip is moved one square to the right and if the coin is tails the chip is moved two squares to the right (unless the chip is one square away from the End square, in which case it just moves to the End square). At that point, any instruction on the square the coin lands on must be followed. Each instruction is one of the following: n1. Move right n squares (where n is some positive integer) n2. Move left n squares (where n is some positive integer) n3. Lose a turn n4. No instruction nAfter following the instruction, the turn ends and a new one begins. Note that the chip only follows the instruction on the square it lands on after the coin flip. If, for example, the chip lands on a square that instructs it to move 3 spaces to the left, the move is made, but the instruction on the resulting square is ignored and the turn ends. Gambling for this game proceeds as follows: given a board layout and an integer T, you must wager whether or not you think the game will end within T turns. nAfter losing his shirt and several other articles of clothing, Alexander has decided he needs professional help-not in beating his gambling addiction, but in writing a program to help decide how to bet in this game.nInputnnInput will consist of multiple problem instances. The first line will consist of an integer n indicating the number of problem instances. Each instance will consist of two lines: the first will contain two integers m and T (1 <= m <= 50, 1 <= T <= 40), where m is the size of the board excluding the Start and End squares, and T is the target number of turns. The next line will contain instructions for each of the m interior squares on the board. Instructions for the squares will be separated by a single space, and a square instruction will be one of the following: +n, -n, L or 0 (the digit zero). The first indicates a right move of n squares, the second a left move of n squares, the third a lose-a-turn square, and the fourth indicates no instruction for the square. No right or left move will ever move you off the board.nOutputnnOutput for each problem instance will consist of one line, either nBet for. x.xxxx nif you think that there is a greater than 50% chance that the game will end in T or fewer turns, or nBet against. x.xxxx nif you think there is a less than 50% chance that the game will end in T or fewer turns, or nPush. 0.5000 notherwise, where x.xxxx is the probability of the game ending in T or fewer turns rounded to 4 decimal places. (Note that due to rounding the calculated probability for display, a probability of 0.5000 may appear after the Bet for. or Bet against. message.)nSample Inputnn5n4 4n0 0 0 0n3 3n0 -1 Ln3 4n0 -1 Ln3 5n0 -1 Ln10 20n+1 0 0 -1 L L 0 +3 -7 0nSample OutputnnBet for. 0.9375nBet against. 0.0000nPush. 0.5000nBet for. 0.7500nBet for. 0.8954

100个球两个人每次最多取五个最少取一个求必胜方法.
100个球两个人每次最多取五个最少取一个，谁能拿到最后一个就赢，求第一个取的人的必胜方法. 这种题目是考虑倍数的问题。每次最多取5个最少1个，这样的话就考虑每次取6， 100÷6=16余4。 先拿的人拿4个，不论第二个人拿几个，第一个人把他凑成6个，这样永远是第一个人取到最后一个。
