请看下面这段代码

int generalGraphMaximumMatching_BlossomAlgorithm()
{
	int matchingCount = 0;
	for (int i = 1; i <= n; ++i)
		matchingCount += !matchedVertex[i] && gerAugmentingPath(i);
	return matchingCount;
}void augment(int u)
{
	while (u)
	{
		int v = matchedVertex[previousVertex[u]];
		matchedVertex[matchedVertex[previousVertex[u]] = u] = previousVertex[u];
		u = v;
	}
}

这是CCF信奥辞典中有关带花树算法的代码片段，不过，变量太——————长了！

所以，在日常中，变量名最好多长呢？
