Android构建失败-java.lang.IllegalArgumentException：已添加：Lcom / google / api / client / escape / CharEscapers;
我只是为我的Android应用程序准备小更新，但是当我尝试构建我的应用程序时（在调试模式下），我得到了这个奇怪的错误。如果更聪明的人可以看一下以找出可能出了什么问题，那就太好了。我正在清理/重建/修复项目属性，但没有结果。我不知道这是怎么回事:(。也许有人在这里发生类似的事情？如果这可以帮助我使用以下库：adMob（4.1.1），openfeint和libgdx。
这是建筑日志：

小编典典您有两次包含相同的jar库。检查您的应用程序和所有引用的Android库，并确保将所有jar都准确地包含了一次。
如果这样做没有帮助，请查看http://tools.android.com/knownissues。具体查看“
构建系统” 部分中描述的第一个问题。

CSU-1908 The Big Escape
CSU-1908 The Big Escape
Description
There is a tree-like prison. Expect the root node,each node has a prisoner,and the root node is the only exit. Each node can accommodate a large number of prisoners,but each edge per minute only one prisoner can pass.
Now,the big escape begins,every prisoner wants to escape to the exit.Do you kNow when the last one escapes from the prison.
Input
There are lots of case.
For each test case.The first line contains two integers n,m（n<=100000,1<=m<=n）,which indicates the number of nodes and the root node.
The next n-1 lines describe the tree.
Output
For each test case,you output one line “Case #%d:%d”
Sample Input
10 2 1 2 2 3 2 4 2 5 1 6 5 7 3 8 2 9 2 10
Sample Output
Case #1:2
题解
题意是给定一个树形监狱，每条边每分钟只能允许一个人通过，给定根节点，犯人逃到根节点就算逃出，每个节点可以存在多个犯人，问逃出的最短时间
这个题就是统计根节点最大子树有多少节点
#include<bits/stdc++.h>
#define maxn 100050
using namespace std;
vector<int> G[maxn];
int sum;
void dfs(int u,int fa) {
for (int i = 0; i < G[u].size(); i++) {
int v = G[u][i];
if (v == fa) continue;
sum++;
dfs(v,u);
}
}
int main() {
int n,m;
int cnt = 0;
while (scanf("%d%d",&n,&m) != EOF) {
cnt++;
for (int i = 1; i <= 100000; i++) {
G[i].clear();
}
for (int i = 1; i < n; i++) {
int a,b;
scanf("%d%d",&a,&b);
G[a].push_back(b);
G[b].push_back(a);
}
int ans = 0;
for (int i = 0; i < G[m].size(); i++) {
int v = G[m][i];
sum = 0;
dfs(v,m);
ans = max(ans,sum);
}
printf("Case #%d:%d\n",cnt,ans + 1);
}
}

delphi – 用于缩略图图像的’hex’或’escape’中的PostgreSQL 9.X bytea表示
我想迁移到Postgresql 9.2并恢复转储,一切正常,除非我尝试检索这些图像：Postgres 9.2使用十六进制表示输出表示而不是Postgres 8.4中使用的转义.
有两种可能的解决方案：更改转义表示的Postgres 9.2设置或通过应用程序更改二进制数据中的十六进制字符串.但什么是最好的解决方案？为什么Postgresql 9.X更改为十六进制表示bytea？
这是一个简单的设置还是有技术原因？
解决方法
- Allow
byteavalues to be written in hex notation (Peter Eisentraut)The server parameter
bytea_outputcontrols whether hex or Traditional
format is used forbyteaoutput. Libpq’sPQescapeByteaConn()function
automatically uses the hex format when connected to Postgresql 9.0 or
newer servers. However,pre-9.0 libpq versions will not correctly
process hex format from newer servers.The new hex format will be directly compatible with more applications
that use binary data,allowing them to store and retrieve it without
extra conversion. It is also significantly faster to read and write
than the Traditional format.
你似乎已经意识到了bytea_output.
