This is a question about the edge coloring of an undirected graph. The specific description is: Given an undirected graph, the edges have two colors, black and white, and have a bunch of anti-color brushes. You can start from any point, go through a number of edges, and then return to the starting point. Find at least how many anti-color brushes are needed to make all the edges in the graph turn white. At the same time, the color of the edges will change and it needs to support two operations: 1. Reverse the color of the xth side (numbered from 0 to m - 1);2. Ask for the minimum number of inverted colors required in the current map. The solution was as follows: 1. ** Feasible Judgment **: For a connected block, if the number of black edges connected to each point is even, there is a solution; otherwise, there is no solution. This conclusion could be proved by the Eulerian circuit. If all the paths that were brushed were black edges, returning to the starting point and painting all the connected black edges once was equivalent to the existence of an Eulerian path in the graph, and the condition for the existence of an Eulerian path in an undirected graph was that all the degrees of the points were even. 2. ** Calculating the answer **: If there is a solution, the answer is equal to the number of connected blocks with black edges. It could be proved by constructing a feasible solution. For example, find a random black point, walk to a continuous black edge, and walk all the way back to this point. For two feasible paths in the same connection block, they can be combined. All the paths of the last connection block can be combined into one. In terms of code implementation, it was generally used to maintain the number of black edges and the degree of each point in each connected block. Buckets were used to store the relevant information for calculation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In novels, whether a woman would forget about being nice to her or not had different manifestations. Some novels might describe how a woman would never forget the good things about a man. This might be due to the woman's delicate feelings, emotional thinking, and other factors. Even if she did not admit it, she would remember the good things about a man. Or because she did not end up with a man who treated her well, this regret made her unable to forget the good things about a man for the rest of her life. However, there were also novels that depicted women forgetting men. For example, when a man's kindness to a woman was too frequent and long-lasting, a woman might take it for granted and gradually forget it. Or when this kindness was too stable and dull, and a woman longed for excitement, novelty, and challenge, she might forget the man's kindness. As time passed, a woman's preferences and needs changed. If a man did not keep up with these changes, a woman might also forget his kindness. However, the specific plot direction depended on the genre of the novel, the plot setting, and the emotions and theme that the author wanted to convey. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
