Time Needed to Rearrange a Binary String

Time Needed to Rearrange a Binary String You are given a binary string $s$. In one second, all occurrences of 01 are simultaneously replaced with 10 . This process repeats until no occurrences of 01 exist. Return the number of seconds needed to complete

1376 TIme needed to inform all employees

这是一个汇报工作时间长度的题 建立MAP,   因为存在层级关系,因此内部为ARRAYLIST,   DFS,  Integer,遍历整体层级数,分情况,如果为-1, 不执行;如果不包括manager i, 建立新ARRAYLIST,表中增加新节点,并把它放在图中。否则,GRAPH包括manger i,增加节点i ,放到图中。    计算图中时间,返回

如何解决报错one of the variables needed for gradient computation has been modified by an inplace operation

  参考资料:   https://discuss.pytorch.org/t/what-is-in-place-operation/16244   https://blog.csdn.net/qq_35056292/article/details/116695219   参考资料二已经说明了问题,对我的情况是使用了+=运算符从而导致了报错。   比如:cost是ReLU函数的运算结果,按照正常的发

921. Minimum Add to Make Parentheses Valid

这道题是典型的括号题,一般来说,括号题用stack做,但是这道题因为太简单了,连stack都不用, 就用int就好了,时间复杂度O(n)。 public int minAddToMakeValid(String s) { int count = 0; int res = 0; for(int i=0;i<s.length();i++){ char c =

Why is Go PANICking?

A panic should always be a last resort, and even then consider a better option! Logging errors with context (cause and message) Expose errors as metrics Expose errors as events So after all the long talk, when is it okay to panic? Panics are somewhat

查依赖的时候发现 ldd: not found 的话,可以用 readelf 喔。

有时候我们需要查找可执行程序的依赖的动态库,我们可以使用 readelf ,比如这样》 [root@RV1126_RV1109:/py-spidev]# readelf -d /bin/ls | grep "Shared library" 0x00000001 (NEEDED) Shared library: [librt.so.1] 0x00000001 (NEEDED)

26 被动语态可省略(by+行为者)/ 被动语态的疑问句

被动语态(by+行为者)可省略 动作的行为者不分明,或不重要,或上下文中提到了行为者时,“by+行为者”可以省略。   1. The information is needed. 信息被需要。被谁需要不重要,所以省略行为者。 2. The book is being read. 书正在被读。 3. The door was opened. 门被打开了。   练习

贪婪算法

贪婪算法: 这是一种近似算法(approximation algorithm)。在获得精确解需要的时间太长时,可使用近似算法。判断近似算法优劣的标准如下: 速度有多快; 得到的近似解与最优解的接近程度。贪婪算法是不错的选择,它们不仅简单,而且通常运行速度很快。在这个例子中,贪婪算法的运行时间为O(n2),其中n
