最新想法: 最多是七位数,而且只有一组输入,完全不用考虑算法复杂度. 直接判断是否为负,并输出符号 巧妙的地方:while循环的下一次再添加逗号.(防止出现,999,991的情况) 婼姐的方法真的很巧妙,能理解,但是不知道如果是自己该怎样想出那种方法. 所以仅仅把婼姐的代码当做学习用,还是得自己来实现啊. 参考了网上很多的博客,真的不好,直接贴代码,思路很差劲的也有.下面这是我觉得最能理解的好方法. 思路分析: 1.a=a+b,当a>1000时,用ans[i++]数组存储a%1000的值,a=a…

这道题算有点难,心目中理想的难度. 不能前怕狼后怕虎,一会担心超时,一会又担心内存过大,直接撸 将三部分分别保存到vector 有意思的在于输出 分别输出第一个的add和num 中间输出nextadd ,换行,add,num 最后输出尾元素的next为-1 #include<iostream> #include<stdio.h> #include<map> #include<string> #include<algorithm> #include…

修改code completion快捷键位CTRL+ENTER,帮助提示函数名称 修改命令行提示符的属性,开启快速编辑模式,方便调试 添加c++11语言标准支持 开启代码调试功能 对输入的字符串进行切割时,可以使用scanf按照指定格式分别输入达到切割效果,比如: //对于这样的输入 3-10 99 11-5 87 102-1 0 //对于这种格式不绝对统一的字符串,可以自己构造相应的scanf分割对应的数据 scanf("%d-%d %d", &t, &num, &a…

1.并查集的定义 在计算机科学中,并查集是一种树型的数据结构,用于处理一些不交集(Disjoint Sets)的合并及查询问题.有一个联合-查找算法(union-find algorithm)定义了两个用于此数据结构的操作: Find:确定元素属于哪一个子集. Union:将两个子集合并成同一个集合. MakeSet,用于建立单元素集合. 为了更加精确的定义这些方法,需要定义如何表示集合.一种常用的策略是为每个集合选定一个固定的元素,称为代表,以表示整个集合.接着,Find(x) 返回x所属集合…
