black side up. You is to write a program, that would search for the minimum number of rounds needed to achieve this goal.InputThe input consists of 4 lines with 4 characters "W" or "B" from each of the denote game field position.OutputWrite to the output file a single integer number-the minimum number of rounds needed to achieve the goal of the game fro M the given position. If The goal is initially achieved and then write 0. If it's impossible to achieve the goal and then write the word "impos

Ultraviolet A 1560-extended lights out Question Link If a matrix is given, 1 indicates that the light is on, 0 indicates that the light is turned off, and no switch is pressed, the four positions around will change. Ask one method to make all the lights dimmed. Two methods:1. Enumeration recurrenceThis is relatively simple. enumerate the first line and then recursive it. If the previous line is on, the next line must be switched down. 2. Gaussian

monic. That is, the coefficient of it highest-order term (AD) is one. Input The input consists of multiple datasets, each in the following format. A m b N This line represents M√a + N√b. The last dataset was followed by a and consisting of four zeros. Numbers in a single line is separated by a single space. Every dataset satisfies the following conditions. M√a + n√b≤4. Mn≤20. The coefficients of the answer A0, ..., ad is between (−231 + 1) and (231−1), inclusive. Output For each dataset, output

I saw a good book when I was learning numerical values. Practice English We should have a better understanding of the Gaussian elimination method. We have done a lot in high generation and linear algebra, but we still need to pay attention to some things when implementing computers, Gaussian elimination method for sele

3SolutionLearn the Matrix tree theorem, which is used to solve spanning tree problem.Matrix One Tree theorem (Matrix-tree theorem) a counting theorem. If the adjacency matrix of the connected graph G is a, the diagonal (i,i) element of a A is changed sequentially to the degree D (v) of Node V, and the resulting matrix is recorded as M, then the cofactor of each algebra of M is equal, and equal to the number of support trees of G. This is the Matrix One tree theorem.To deal with the determinant,

After each switch is pressed, the switch is reversed in four directions. If you want to disable all the switches at the end, follow these steps. 0 indicates not to press, 1 indicates to press. solution : There are only 5*6 switches in total. For each switch, set its final status to X5, and the top, bottom, and left switches to x1

In the initial state, both accounts have zero points. Each game uses a low-score account to compete. A probability of winning a game is P, the score of the corresponding account increases by 50 points. Otherwise, the score of the co

geometric series summation formula, get:$ $ans \times (i-f) =\frac{p}{q}\times{s}$$where \ (i\) is the unit matrix, the size is \ (n\times{n}\), the diagonal is \ (1\), other locations are \ (0\).Only \ (ans\) is unknown, and this is a linear equation group.The problem, however, is that the coefficients of the i\ equation are \ (f\) (i\) columns instead of rows. So we invert the ranks of \ (f\), or write an awkward Gaussian
