how many one to one and onto function? M!/N!? So, you are saying that, when M=N, the number of ways of one to one mapping is 1? |

find the recurrence relation of a string if n=0, there's no string at all. which mean the number of occurrence of a string that not contain 010 is 0. Honestly, I don't rly get this problem too :D |

Showing that $R$ is an equivalence relation on $X \times X$ I got the reflexive and symmetry part, but still stuck on the transitivity part |
