The file “/xx/xxx/xxxx.dita”is outside the scope of the input dita/map directory.

如果路径没错的话,就是引用的内容不在这个ditamap之内,也就是引用的内容不能在被引用时单独生成。 还有个错误:编辑器里面可以正常加载路径,但dita-ot始终说找不到的某个dita文件的错误,我以为是缓存的问题,其实可能是之前引用的地方不止一处,文件加或者文件改名之后没有将其他地方改完,可以用f ......

The 2023 ICPC Asia Hefei Regional Contest Test D. Balanced Array

Preface 这题赛场上出了个关键点基本都想到的做法,但因为一个地方卡住了没过去导致不得不选择弃掉这道题 赛后补了下发现\(O(n\log n)\)的做法是只差临门一脚了,但\(O(n)\)的做法还是trick性挺强的 Solution 首先考虑枚举\(k\),不难发现此时合法的前缀一定是个连续的 ......

【pwn】[HGAME 2022 week1]enter the pwn land --数组下标修改,栈溢出

查保护 然后ida看代码逻辑 来到关键函数,这里存在栈溢出漏洞,但是这是数组循环一个字节读入,我们看一下i的地址 发现i的地址在rbp上面,所以我们构造payload肯定会把i的值给覆盖了,所以payload在构造时需要修改一下i的值,让我们的payload继续读入到正确位置,然后就是简单的ret2 ......
