|采纳率75%几年前,我和妻子买过一件廉价的家具,在最初的几个月里,它欺骗了所有人--它看起来很舒服,也能正常使用,给人留下很好的印象,我们也感觉它和我们的房间很协调.但随着时间的流逝,边缘处薄薄的一层覆盖面开始脱落.它不再令人印象很好,但至少它是坦诚的!事实上,不管你喜不喜欢,在我们聪明的掩盖下,我们都只不过是个硬纸板.所以在我们做别人的法官随意评审他人之前,我们应该明智点花点时间在镜子里看看自己的摸样.能毫无保留的审视自己越多,我们就越会想去并有能力去原谅他人的缺点,越多的原谅他人,我们就越能明白生活的真谛.

acm The Drunk Jailer
题目·
A certain prison contains a long hall of n cells, each right next to each other.
Each cell has a prisoner in it, and each cell is locked.
One night, the jailer gets bored and decides to play a game. For round 1 of
the game, he takes a drink of whiskey, and then runs down the hall unlocking
each cell. For round 2, he takes a drink of whiskey, and then runs down the hall
locking every other cell (cells 2, 4, 6, …). For round 3, he takes a drink of
whiskey, and then runs down the hall. He visits every third cell (cells 3, 6, 9,
…). If the cell is locked, he unlocks it; if it is unlocked, he locks it. He
repeats this for n rounds, takes a final drink, and passes out.
Some number of prisoners, possibly zero, realizes that their cells are unlocked and the jailer is incapacitated. They immediately escape.
Given the number of cells, determine how many prisoners escape jail.
Input
The first line of input contains a single positive integer. This is the
number of lines that follow. Each of the following lines contains a single
integer between 5 and 100, inclusive, which is the number of cells n.
Output
For each line, you must print out the number of prisoners that escape when the prison has n cells.
Sample Input
2
5
100
Sample Output
2
10
我的答案
#include // 0 lock,1 unlock
#include
int main()
{
int i,j,n,m;
scanf("%d",&n);
while(n--)
{
scanf("%d",&m);
int count=0;
int a[100]={0};

|采纳率82.6%1.数组应该声明至少a[101]
2.if(a[j]==0) a[j]=1;
if(a[j]==1) a[j]=0;
不对,这么做没意义,永远会让数组的值为0.把if(a[j]==1)改为else
改正后是没问题的,但是没必要这么麻烦.
解题思路:编号为1的门只为1的倍数,所以只执行了一次操作,所以其最后的状态是开,编号为2的门只为1和2的倍数,执行了两次操作,其最后的状态是关,编号为3的门为1和3的倍数,执行了三次操作,其最后的状态为关,编号为4的门为1、2、4的倍数,执行了三次操作,其最后的状态为开.以此类推,如果编号为一个数的平方数,则其执行操作的次数为奇数次,其最后的状态为开.于是只要求出小于这个数的正整数中有几个数是平方数即可.
代码如下:
#include
#include
int main(void){int n,a,on;
scanf("%d",&n);
while(n--){
scanf("%d",&a);
on=(int)sqrt(a);
printf("%dn",on);
}
return0;
