### 10220 wa confused

i honestly don't know what could be wrong with my solution - i pregenerate the factorials (0! -> 1000! - not even stripping the zeros from the end), calculate the sums of the digits, the program runs in time (less than a second), but still it's wa.... there cannot be tricky cases, the standard input...

However, you may want to think about whether you actually need storage for MX*MX = 25000000 edges in this problem. thanx for the input, I know that I would only need to store MX-1 edge - but I tried to be lazy and not bother with a seperate edge structure. However, thanx for the lesson, I really di...

### 10459 - The Tree Root

I believe it's more of a C language problem than algorithm, but if you've done this problem, you might be able to help me.

### Array size limit in C???

hi, I encountered this problem while trying to solve problem 10459. The description says that the maximum number of nodes is 5000, and that's what gets me into trouble. Here are all the variables I use: [c]#include <stdio.h> #define MX 5000 struct _node { int id,out,cost; struct _node *adj[MX]; }; m...

### wonder what's wrong here

hello all, I'm wondering why I got stuck on this problem... Is there some fancy input I don't handle quite right or I don't handle the multiple input well enough? all comments are appreciated [c]#include <stdio.h> #include <string.h> #define MX 81 int comp(char *what,char *where,int l) { int i=0; wh...

### why fibonacci?

hei,

I spent some time on the problem and I just couldn't figure out how to solve it, but after looking at this thread, it seems that it is using the fibonacci numbers - could someone explain me why or just recommend some book/website? thanx a lot.

thanks, though I just feel even more confused - I thought I got the rules, but it seems I did not in the standard input, the answer for the case 2#101##123# is yes - why? isn't there supposed to be only one number per line? or can you join additional number in the form _number_ (base#digits#)#_numbe...

### understanding of the problem

just a question, which I hope would clarify the problem (donno if it's just me, but I am confused by the description of the problem): what should be the output for the following input? 3 123##2#01001# 10#456##3#1210# 9#456##2#1210# my guess would be yes yes no let me know if I am right or wrong plea...

### 10179 - algorithm

I just would like to ask someone if I am going on the right track or not... First I figure out if the denominator is prime or not. If it is, the output should be n-1, right? (by the way, what should be the output for n=1? 0 or 1?) Otherwise, I get all the primes, smaller than n^0.5, which divide n a...

anupam, I got AC - it is a real frustrating problem! Once I had a physics teacher and noone ever could score 100% on his tests, 'coz he would trick us... for instance, if in class he gave us all data in meters, then he would change it to centimeter in the test or something like that... You just need...

pls, could somebody help me now that the judge is judging correctly? I keep on getting TLE, though I dinamically store the results from previous calculations and limit the obviously impossible cases (when the value of t is less than 4). I have a feeling that I might not deel correctly with the input...

### Re: 10106 product

hmm, let's see... have you tried multiplying with zero? and what's the upper limit for the numbers you can deal with? I got AC on it and I prepared to deal with any number less than 10^1000... maybe you can't use long long and those kinda things :)route wrote:any tricky inputs for this question ?
