HDU 2842 Chinese rings (with constant matrix + rapid matrix power) ACM Address: HDU 2842 Chinese rings Question:A Chinese ring, the K ring to be unlocked first needs to be unlocked before (K-2) a ring, and leave the (k-1) ring. It takes at least a few steps to unlock N rings. Analysis:If F (n) is set, the N ring is unlocked.1. Due to the game rules, the N-Ring cannot be completely unlocked at once, or n-1 N

. Mechanical programmer (Drone Programmer)Many programmers are mechanical programmers who are trying to fill their wallets in nine to five. They don't want to be exposed to new technologies and to avoid learning things. Many companies or development teams have many of these mechanical programmers because they are cheap, but don't know that more expensive programmers are really cheaper.5.

The problem is to use a matrix of the knowledge point of the law, very ingenious, but do not understand the nature of the matrix is difficult to think of. There is also an array inside the struct that cannot be too large, or it will explode. That is a*b*a*b*a*b*a*b ... A*b can be converted to a * (B*a*b*a*b*a*b ... A) *b, that is, ans = b*a*b*a*b*a, the last a*ans*b on the line. #include

/* Test instructions: give you a matrix with numbers only 0 and 12, where the columns can be moved arbitrarily. Asking how to move can make the element in a sub-matrix all 1, and find out the area of the largest sub-matrix. Each row is processed and then superimposed, to each row with Num[i] Note how many 1 for example: 1 0 1 1 num[i]
