i think if you try to init x and y as 10e-6,you will get AC.
GOOD LUCK.

yes,i can use scanf(). but i don't know much about the function in C. In UVA, the most input is terminated by End Of File. when i use stream, cin will throw an exception when it read EOF, i use [cpp] while (cin >> a)[/cpp] to find the End Of File. If i use scanf(), how should i write [c]while (scanf...

Oh,my god.
yes,you are right, i use "Choice",then ACC.
Thank you.

I use TC and VC++. They have the same problem.
My OS is Windows.
can i include <iostream>?
i always use iostream.h.
Thank you.

I am writing a program about clock these days. but there are a little problem about input, then i have writen a test program.And i have found a strange thing. This is my code: [cpp] #include <iostream.h> void main() { int a; while (cin >> a) cout << a << endl; } [/cpp] input: 15 00 01 02 05 07 08 09...

I have tested my code for many inputs,and i have been careful to the output format. But it always gets WA. :( Please help me,Thank you. :D :D :D [cpp] #include <iostream.h> #include <stdio.h> void main() { long int step,mod,i,seed,j; long int flag; while (cin >> step >> mod) { for (i = 0;i < mod;i++...

why my answer always gets PE? [cpp] #include <iostream.h> #include <stdio.h> int main() { long n,i,b; while (cin >> n) { b = 1; for (i = 1;i <= n;i++) { b *= i; while (!(b % 10)) b /= 10; b %= 100000; } while (!(b % 10)) b /= 10; b %= 10; printf ("%5ld -> %ld\n",n,b); } return 0; }[/cpp]

i have checked my code and got AC
thanx

oh,i see.
and i have changed a new way to slove this problem and got accepted.
Thanx.

2 is the right answer?
why?
i think 3 is the right answer. And my code get the answer 3.

Please help me! why WA? [cpp] #include <iostream.h> #include <stdio.h> int max = 104; int k; int sum[105]; void main() { char c; int i,j,k1,x; int sum1[105]; k = max; while (1) { for (i = 0;(c = getchar()) != '\n';i++) sum1 = c - 48; if (!sum1[0]) break; k1 = i - 1; j = max; x = 0; for (i = k1;i >= ...

Why my code is WA? Please help me! [cpp]#include <iostream.h> struct node { int num; node *next; }; node *head,*last; int dele () { node *p; p = head; head = head -> next; delete p; return 0; } int swap () { last -> next = head; last = head; head = head -> next; last -> next = NULL; return 0; } int ...
