实验要求: Objective: To know how to generate noise images with different probability density functions (distributions). The noise images are useful in simulation for image enhancement and image restoration. Main requirements: Ability of programming with…

添加主键时,出现错误:[Err] 1068 - Multiple primary key defined #增加主键 ) not null; ; alter table my_test add primary key (phone_number); #[Err] 1068 - Multiple primary key defined 这是因为已经存在主键 (id) 了,需要先删除原来的主键,再设置新的主键 显示主键: show keys from table_name; #显示主键…

记录个自己遇到的问题: 上星期项目刚拉取下来的时候运行没有任何警告,晚上回去vscode提示更新新的东西,当时没管就立即更新了,第二天重启项目直接一大堆警告冒了出来: There are multiple modules with names that only differ in casing.This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.Use equa…

本题传送门 本题知识点:深度优先搜索 | 宽度优先搜索 题意很简单,让我们找一个只有1和0组成的十位数是n的倍数的数. 这题一开始吓到我了--因为Output里说输出的长度最长不超过100位???那是不是要用字符串了?不过貌似在[1, 200]里,他们的倍数好像都在18位内,即用unsigned long long就可以解决.(BUG?) 若想学习输出100位的可以看看这篇博客 数据很小. // POJ 1426 #include<iostream> #include<cstdio>…

–allmatches  Remove all versions of the package which match PACKAGE_NAME. Normally an error is issued if PACKAGE_NAME matches multiple packages. 造成这个问题的主要原因是套件被重複 (强制) 安装了两次以上. [root@testbed bin]# rpm -e --allmatches subversion-1.4.2-4.el5…

We can configure multiple HttpSecurity instances just as we can have multiple <http> blocks. The key is to extend the WebSecurityConfigurerAdapter multiple times. For example, the following is an example of having a different configuration for URL’s…

Problem Description 求n个数的最小公倍数. Input 输入包含多个测试实例,每个测试实例的开始是一个正整数n,然后是n个正整数. Output 为每组测试数据输出它们的最小公倍数,每个测试实例的输出占一行.你可以假设最后的输出是一个32位的整数. Sample Input 2 4 6 3 2 5 7 Sample Output 12 70 注意:用gcd求最小公倍数是,若两个数相乘后再除以最大公约数,可能会导致数据超限,从而wa,因此应改变一下运算的顺序 #include<…
