dpsk给了几个关于Linux系统核心的代码 但是编译错误,不行
1.试了试直接cout,不行 2.把头文件换成cstdio,namespace去掉,直接printf,不行 至今还在寻找解决方案
内存搞错了
#include <iostream> #include <string> int main() { stdios_basesync_with_stdio(false); std::cin.tie(NULL); }
刷刷刷!!!错题!!!
汉诺塔的步数公式是2^n-1 是的你没看错,就这么 简单!
我到底是个啥 AC狗是什么物种? 这个问题不光我们搞不清楚,AC狗自己也弄不拎清。 如果说AC狗是一种狗,世界上没有直立行走的狗,狗都是四肢着地,而AC狗是直立行走,有明显的上下肢区别。 (还会用手拿放大镜称体重) 如果说AC狗是人,他和人长得又不太像,鼻子、耳朵似乎都不是人类器官的形状。 对此AC狗很苦恼,不知道自己究竟是个啥。 他决定听听大家的看法,想听听大家认为他是啥。为此,AC狗找了许多人询问他们的意见,有说AC狗是狗,也有说AC狗是人,还有说AC狗是赛亚人。 问了半天也得不到一致的结论。最终,AC狗决定让大家投票,认为自己是哪种东西的票数多,自己就是什么东西。 请写程序帮助AC狗统计票数,判断他到底是个什么东西。
小码君想在学校中请一些同学一起做一项问卷调查,为了实验的客观性,他先用计算机生成了 N N 个 1 1 到 1000 1000 之间的随机整数 ( N ≤ 100 ) (N≤100),对于其中重复的数字,只保留一个,把其余相同的数去掉,不同的数对应着不同的学生的学号。然后再把这些数从小到大排序,按照排好的顺序去找同学做调查。请你协助小码君完成“去重”与“排序”的工作。
十二点到了,小码君要去食堂吃饭,但他的同学们并不是这么想的。 “小码君,帮我带一份咖喱鸡” 现在总共有n个同学需要小码君带饭,不过他们只想吃以下三种午餐:咖喱鸡、黄焖鸡、椰子鸡。 每个同学只会想吃其中的一种午餐,请你帮小码君统计一下,每种午餐要带多少份。
这™是作业?
是哪些神金在刷错题啊(
太水了
今天ac狗要参加短跑比赛,所有选手从起点出发前往终点,终点与它们的距离为 n − 1 n−1 个单位长度。比赛虽然叫 "短跑" 比赛,但是并不限制只能用跑的,ac狗比起跑步,更擅长跳跃。 它每 1 1 秒可以跑动 1 1 个单位长度,但是也可以花费时间在原地蓄力。例如,当 ac 狗在 x x 处蓄力了 i i 秒时,它下一次就可以花费 1 1 秒跳到 x + i 2 x+i 2 处,或者也可以选择继续蓄力。 当然,完成比赛是需要用身体接触红线的,因此ac狗不可以跳过终点(也就是越过 n n)。 小码君很聪明,在比赛前就可以计算出ac狗最快多少秒可以到达终点,那么这个值是多少呢? 8 粉丝数
