I'm a beginner of C++. I checked all the post about 444. But they seems irrelevent with my problem. Can anyone help me? This is my code
#include <iostream>
#include <string>
using namespace std;
int main(){
int i,j,number,output;
string input,o;
char ch;
string digit="0123456789";

while (ch=cin.get()){
input=ch;
o="";
while((ch=cin.get())!='\n'){
input+=ch;
}
if (digit.find_first_of(input[0])>=digit.length()){ //message
for (i=input.length()-1;i>=0;i--){
number=input;
if (number<100)
output=(number%10)*10+number/10;
else
output=(number%10)*100+((number%100)/10)*10+number/100;
if (number%10==0) cout<<"0";
if (number==100) cout<<"0";
cout<<output;
}
cout<<endl;
}
else{
while (input!=""){
if (code.find(input.substr(0,3))>code.length()){
number=(input[0]-'0')+(input[1]-'0')*10;
input.erase(0,2);
}
else{
number=(input[0]-'0')+(input[1]-'0')*10+(input[2]-'0')*100;
input.erase(0,3);
}
ch=char(number);
o.insert(0,ch);
}
cout<<o<<endl;
}
}
return 0;
}
the email only says:
Your program has died with signal 6 (SIGABRT). Meaning:
Abort signal from abort()
Before crash, it ran during 0.002 seconds.
And I really don't know what to do. Please help. thank you!

Same problem as him! Also in Java. There's no mistake in my code. I guess there is something wrong with the oficial output.

You should post in existing posts aboute these problems...
I cant help you with java... but in 445, you cant print '\n' in the last output. I mean, the program output doesnt end with newline.
in 444, try this input
Code: Select all
This is a problem from volume four.
One is to write an encoder-decoder program here.
IS THIS A VALID LINE ?
To B or not TO be is the QUESTION.
to B or NOT to B is tautology !

A reply after more than 3 years. However please check the bug and suggestions forum regarding problem 445. Thanks for the input for problem 444. I will check it out when I have time.

Thanks for the input. My PE code up there crashes for blank lines. But it should have been a WA rather than PE if there had been blank lines in the input?

Ok, I am certain there are extra blank lines at the end of judge input, but not in the middle, as mogers's sample input suggests. Can anyone verify this? Thanks.

Hello everyone... I'm a novice in C and C++ (and English grammar) please help me about this problem. I tested my code with more than 50 test cases recently at all topics about this problem and get correct Outputs.
BUT I STILL GET WA.
but I still get WA.
Can anybody give me some test cases that my code generates wrong output.
here is my code :

Hi Rio and tanks 4 ur attention. but I saw all threads about this problem recently and read all of them carefully and check my Algo with some test cases that I saw there and my Algo works correctly with that.
could u explain for me what's
WRONG with
is_In_Set() sub or give me some
test cases that my Algo works WRONG with it.
I can't identify what's wrong with is_In_Set() sub:( .
thanks again.
