Problem description in a rectangle square of 2 × N, fill the square with a 1 × 2 bone card, input N, and output the total number of layout solutions.
For example, if n = 3, it is a 2 × 3 square. There are three methods for laying the bone card, for example:
The input data is composed of multiple rows. Each row contains an integer N, indicating that the rectan

X-2 Distribution
Random Variable X is an independent standard normal distribution variable ~ N (0, 1), that is, E (x) = 0, VAR (x) = 1.
Q1 = X12, Q1 is a chi-square distribution, recorded as, degree of freedom is 1
Q2 = X12 + x22, Q2 is a chi-square distribution, recorded as, degree of freedom is 2
And so on. The figure shows the distribution chart of Chi-square.

Magical Magic SquareTitle DescriptionMagic Square is a very magical n*n matrix: It is composed of digital three-way,......, n*n, and the sum of the numbers on each row, column, and two diagonal lines are the same.When n is an odd number, we can construct a magic square by the following methods:First write 1 in the middle of the first line.Then, fill in each number of K (k=2,3,..., n*n) in the following way
Title: Square Number of rowsXiao Ming is looking at the number 203879 in a daze.Originally, 203879 * 203879 = 41566646641What's so magical about that? Carefully observed, 203879 is a 6-digit number, and its number on each digit is different, and it does not appear on all digits after the square to make its own number.There is a 6-digit number with this feature, please find it!Let's summarize the screening r

Implement Pow (x, n).This problem let us ask X of the N-square, if we simply use a for loop to X times their own n time, it would be too easy to think on the Leetcode, a word describing the pattern Tucson broken AH. OJ cannot pass because of timeout, so we need to optimize our algorithm so that it can work out the results more efficiently. We can use the recursive return binary calculation, each time the n is reduced by half, so that N will eventually

We use the repulsion principle.First, the number that cannot be sent (that is, the number that contains the square factor), and then the total amount minus it.So, there is a number of squ
Chuang Tzu told such a story: The Emperor of the South China Sea, the emperor of the North Sea is called suddenly, the central Emperor called Chaos. Evanescent and suddenly often together in the chaotic ground meet, chaos treats them very well.
