Java structure for set of sets that have to union? (for Kruskal's Algorithm) I have to implement Kruskal's Algorithm in Java. I have the part that I get the edges ordered by weight, but I am a little lost when I have to think the structure to save the sets of each tree. I thou...

刷LeetCode之前的基础:本科非CS,与CS相关的课只有一门C++,跟过Coursera上的Algorithm课程,学过基本的数据结构。胡乱看过Algorithms的前几章和CLRS书,前者跟着课看的话大部分能看懂,后者很多看不懂。扫过CLRS的一些习题但太菜了做不动。硕士转了CS,也没上过算法课和数据结构课,做的是机器学习方向。这时候做Leet...

When mice actively sought rewards, BLA activity in resilient mice showed robust discrimination between reward choices. By contrast, susceptible mice exhibited a rumination-like signature, in which BLA neurons encoded the intention to switch or stay on a previously chosen reward. Manipulation of vCA1 ...
