Solution: The practice of the subject is really a lot ah, probability DP, expect DP, of course, and the moment by black technology ~is to run the AC automaton first, make the transfer matrix, and then squared 50 times
Test instructions: n * N 01 Matrix, can do two operations: ① two lines exchange; ② two columns. Ask if you can go through several operations, so that the matrix from the top left to the bottom right diagonal is all 1. The problem: The first line Exchange, the column exchange when the relative position of the element will not change, the matrix is equal to the exi

a, and a [n-1] is not met, because the n times cannot be passed to a. The other type is that the n-1 times are not in the hands of, the nth time the ball was held and then passed to Jia had a [n] method, according to the addition principle a [n-1] + A [n] = (K-1) ^ (n-1) A [1] = 0 is used because a is the serving operator.
Idea: An (N indicates the number of times that the ball is passed n times and the number of times that the ball is returned to the armor plate );
A1 = 0;
A2 = (K-1) ^ 1-a1;

Notice how to change it, but if you put a black square on the diagonal, the black squares of its original row will not work.So to choose the N group of not heavy row and column combination, here with the Hungarian algorithm to do two-figure matching (with time stamp optimization)#include Bzoj 1059: [ZJOI2007] Matrix game "Hungarian algorithm"
Test instructions: Finding the largest sub-matrixAnalysis: Directly using the formula of the most large matrix to do time-out. A change of mind, the problem with the previous question 1506 has a relationship, first of each layer to calculate the maximum height of each element can reach, and then with 15,061 samples. The DP staging data is used for height and area two locations. For the height of the double cycle, and then each layer for the bottom are
