That was all I had to change! I was under the impression that the key could be something other than 7, but I was wrong.

Thank you much pochmann!!

Here's my code so far. Am I on the right track?:

#include <stdio.h>
#include <string.h>
#include <fcntl.h>
#include <ctype.h>

main()
{

char coded[3000];
char decoded[3000];
int length, i;
int key;

gets(coded);
key = coded[0] - '*';

do
{
length = strlen(coded);

for(i=0;i<length;i ...

Can anybody give me some sample input to use to test my program for #458? My program works with the sample input given on the website, but I still get a W.A. What's the tricky input on this one??

I'm looking for any tips on #495. Clearly, the 5000th Fibonacci number is going to be huge, so what data type can store that number? Any tricks to calculating it quickly? Any help would be appreciated.

I got it! Yay! I just had to change my data type for storing the intermediate results from a long double to just a double. Thanks everybody for your help.

You're right, I hadn't considered that! That'll teach me to read the problem more carefully. So, I fixed it to terminate when a 0 is read for num1 && num2. Unfortunately, I still get a Wrong Answer.

P.S. Thanks Adrian for helping me on this one.

When testing my program using sample input, I get correct answers. Yet, when I submit my program, it says I have a wrong answer. What are the tricky inputs?

I've tried using sample inputs of num1 = 2^31 and num2 = 2^31, and num1 = 2^31 and num2 = 1, which seem to be about the two limits since the ...

Thanks Adrian! Your line of code took care of my runtime error problem. But now I got a wrong answer. I think perhaps I'm using the wrong data type.

Any clues as to what the tricky input the judges uses?

Perhaps using Pascal's Triangle would be a better way to approach this problem????

Here is the code I submitted. It gives me the right answers to the sample input on my computer, but I get Time Limit Exceeded when I submit it for judging. Any input would be appreciated:


#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>

main()
{
int num1, num2 ...

Can anybody offer any hints to solving problem #530 - Binomial Showdown? My first attempt at solving this problem resulted in an exceeded time limit. Any tips?

Just got accepted! Thanks for reading.

Okay, I started off on problem 100 and thought I had it solved pretty quickly. Using the sample input given on the problem page, I ran the program on my machine and it arrived at the same output listed in the Sample Output. Unfortunately, when I submitted it, the judge says I have a "wrong answer ...
