B - Pentagon 难度: ⭐ 题目大意 给定一个正五边形, 其顶点为ABCDE; 给定端点a, b, c, d; 问a, b之间的距离和c, d之间的距离是否相等; 解题思路 两个端点之间的距离就看两个端点之间隔了几条边就行; 并且因为是五边形, 隔x条边和隔5-x条边是等价的; 神秘代码 ......

B - Glass and Mug 难度: ⭐ 题目大意 给定两个杯子A, B; 如果A杯子装满水了, 则把A杯子里的水倒掉; 否则如果B杯子空着, 则把B杯子装满水, 否则就把B杯子里的水倒进A杯子里, 直到B杯子空了或者A杯子满了; 问重复上述操作n次, 最后两个杯子里的水各位多少; 解题思路 ......
Educational Codeforces Round 160 (Rated for Div. 2) A~C
A. Rating Increase 题意： 将一个字符串分成两个整数a和b，要求没有前导0，且a < b 思路： 遍历字符串s，若当前位置不是0，则拆分字符串，比较大小 // #include <bits/stdc++.h> #include <iostream> #include <string ......
Educational Codeforces Round 160 (Rated for Div. 2)
基本情况 A题秒了。 B题卡了实在太久，BC题最后虽然都过了，但是耗时太久。感觉C对我来说更好写。 B. Swap and Delete 经典+3。 总是一条路偏要走到黑了才会想着换思路，早该换了。 一开始想了一大堆乱七八糟的思路，但都错了。 后面往简单了想，这题毕竟最后必须要左对齐的，直接从左往右 ......

Queries for the Array 题解
前言 这场 CF 是我赛后打的，vp 赛时没做出来，后来发现是有个地方理解错了，有一些细节没有考虑到。现在换了一种思路来写，感觉更清晰了。 做法 首先需要动态维护三个变量，\(cnt\) 和 \(finishsort\) 和 \(unfinishsort\)。这三个变量分别表示当前数字的个数，已经排 ......

LightGCL Simple Yet Effective Graph Contrastive Learning For Recommendation论文阅读笔记
Abstract 目前的图对比学习方法都存在一些问题，它们要么对用户-项目交互图执行随机增强，要么依赖于基于启发式的增强技术（例如用户聚类）来生成对比视图。这些方法都不能很好的保留内在的语义结构，而且很容易受到噪声扰动的影响。所以我们提出了一个图对比学习范式LightGCL来减轻基于CL的推荐者的通 ......
