2) strongly connected components 强连通分支 1. Also,thestrongly connected componentsand strong connectedness of product spaces are studied. 在L-fuzzy拓扑空间中引入了强连通的概念,证明了强连通的一些基本性质,并研究了强连通分支和乘积拓扑空间的强连通性,得到了一些好的结果。
这道题和305. numbers of islands II是一个思路,一个count初始化为n,union find每次有新的edge就union两个节点,如果两个节点(u, v)原来不在一个连通图里面就减少count并且连起来,如果原来就在一个图里面就不管。用一个索引array来做,union find优化就是加权了,每次把大的树的root当做parent,小的树的root作为...

(updated June 2024), global cellular IoT connections grew 24% YoY in 2023, strongly surpassing the growth rate for global IoT connections. This growth is due to the adoption of newer technologies such as LTE-M, NB-IoT, LTE-Cat 1, and LTE Cat 1 bis, as older technologies such as 2G ...
