There are n mines. The starting position of a person is 1. The probability of each step is p. The probability of two steps is 1-p, and the position of n mines is given, ask the probability of successful exit from the minefield.
In high school, it should be a simple step-by-step multiplication to calculate the probability. That is, the probability that ea

Consider the a[i] position of thunder, then the probability of safe passage is to reach f[a[i]+1] The probability is: f[a[i]-1]* (1-p).Because A[i] is very large, so we want to segment with a matr

Ideas:
Divide the entire process into stages for processing:
1 ~ A [1]
A [1] + 1 ~ A [2]
............
A [n-1] + 1 ~ A [n]
Then, you only need to find the probability of stepping on the thunder each ti

Address: POJ 3744
A linear probability DP recursive formula. Dp [I] = p * dp [I-1] + (1-p) * dp [I-2]. However, the I value is too large. Therefore, it can be divided into n times, and the pure recursive process of each intermediate process is optimized by the matrix Rapid power. It is easy to think of the Rapid power of a matrix.
The Code is as follows:
