Set entrySet (): returns a Set composed of all key-value pairs in the Map. Each Set element is a Map. Entry (Entry is an internal class of Map) object.
Object get (Obejct key): returns the value corresponding to the specified key. If the Map does not contain the key, null is returned.
Boolean isEmpty (): checks whether the Map is null (that is, it does not contain any key-value

There is only one simple path between any two points ⇔\leftrightarrow tree So is to make the remaining points to form a tree, it is easy to find, as the number of lattice, the number of edges increased faster than the point, and K K will not be very large. So when the n∗m n*m is too big, it is impossible to make a tree. Rough estimate, 5∗105 5*10^5 is no solutio

Tip 13: Avoid redefining arraysTry to avoid Redim arrays. From a performance-sensitive standpoint, if your computer is limited by physical memory, it's best to start by setting the dimensions of the array to the worst-case scenario-rather than setting the dimension to the best scenario, and then redefining the dimensions as needed. This does not mean knowing that you don't need that much and that you should allocate too much memory.The following code shows that you do not nee
