Description 两个字符串 \(A\) 和 \(B\)，若 \(A\) 是 \(B\) 的前缀且 \(A\ne B\)，则称 \(A\) 是 \(B\) 的 proper 前缀。两个字符串 \(C\) 和 \(D\)，若 \(C\) 是 \(D\) 的 proper 前缀且 \(D\) 是 \(CC\) 的前缀，则称 \(C\) 是 \(D\) 的周期。给出一个字符串，求它的所有前缀的最大周

excel字符分开合并下划线后第一个字母大写

1、字符串通过下划线分列(选中这一列->数据->分列)，每列首字母大写(=proper(a2))，在合并(=A3&B3&C3) 2、先=proper(),此时字符串里面有下划线(Dp_Cfoam)，然后复制出来只取数字， upper/lower(全部为大写或小写) proper(c5),全部首字母大写 LOWER(MID(C5,1,1))&RIGHT(C5,LEN(C5)-1)

1154 Vertex Coloring (25 分)

A proper vertex coloring is a labeling of the graph's vertices with colors such that no two vertices sharing the same edge have the same color. A coloring using at most k colors is called a (proper) k-coloring. Now you are supposed to tell if a given

j-link The connected j-link is defective. proper operation cannot be guaranteed 问题解决

在更新完j-link的驱动之后报错 The connected j-link is defective. proper operation cannot be guaranteed。经过查找资料之后发现是j-link固件和j-link驱动程序不兼容引起的问题。可以升级j-link固件或者降低j-link驱动程序的版本来解决。我这边使用的是升级j-link固件

initQRCodeForInputByteSize cannot find proper rs block info (input data too big?)【将base64字符串转为图片】

前言之前的同事误认为二维码是app侧自己生成,直接将base64字符串作为二维码的内容去生成，一张二维码容不下这么长的内容。就生成失败了。其实只要直接将base64字符串转图片。 initQRCodeForInputByteSize cannot find proper rs block info (input data too big?) code
