I know the trick of finding the repeated sequence of [the last digit of m] poweres n to get the same correct answer, but could anyone please explain why the last two digits of n is enough?

My code is: #include <iostream> using namespace std; int FindMinBase(char *number) { int max=0, temp; char *current=number; while(*current!='\0') { if(*current>='0' && *current<='9') temp=(int)(*current-'0'); else temp=10+(int)(*current-'A'); if(temp>max) max=temp; current++; } if(max==0) return 2; ...

About q445

The following is my code, could anyone figure out why I always got WA? [cpp] #include <iostream> #include <cctype> using namespace std; void main() { char read_in[3000], *ptr; short repeat, i; cin.getline(read_in, 3000); while(cin.good()) { ptr=read_in; repeat=0; while(*ptr!='\0') { if(isdigit(*ptr)...

[quote="xenon"]No, the sample output is right. The order in which the terms are counted is:
[code]
1 2 6 7 15
3 5 8 14
4 9 13
10 12
11
[/code]
for the first 15 terms. It's a zig-zag![/quote]

I thoutht I made the same mistake!
But I think the description should be a little clearer.

about "t_base"

I'm sure I've prevented "t_base" from being 1, since before this part I have an "if" to handle the problem directly when there is only ONE working cat. For example, when I input "64 1", I will get "6 127", right answer, isn't it? Or did I ignored any other "except" situations? :roll:

Floating point exception

I have tried lots of inputs (partly from the Problemset Archive and partly from some discussions about q107) by hand and it always gave me right answers. I can't figure out why I should get "float point exception." The followings are the considered most "fragile" part in my code. I hope someone can ...

The discription of the problems

Sometimes the description of the problems really confuses me. For example, q477 should be a very easy one; after I enlarged my array size (for example, double something[10000]), I got "accepted" response. However, the description didn't mention it would be rejudged. Insted, it clearly mentioned ther...
