I'm getting WA. On my pc i've tested with several inputs...don't know why it's showing wrong answer. I have a hint that may be it's problem with newline. Here's my code..plz give some valuable input.

Code: Select all

#include<cstdio>
#include<iostream>
#include<vector>

using namespace std;


vector<int> map;
void add(int ch)
{
     map.push_back(ch);
 }

int main()
{
    map.reserve(100);
    //start from upper corner
    add('`');
    for(int i=0; i < 9 ; i++)
    add(i+1);  
    add(0);
    add('-');
    add('=');
    //second row
    add('Q'),add('W'),add('E'),add('R'),add('T'),add('Y'),add('U'),add('I'),add('O'),add('P'),add('['),add(']'),add('\\');
    //third row
    add('A'),add('S'),add('D'),add('F'),add('G'),add('H'),add('J'),add('K'),add('L'),add(';'),add('\'');
    //last row
    add('Z'),add('X'),add('C'),add('V'),add('B'),add('N'),add('M'),add(','),add('.'),add('/');   
    
    
    vector<int>::iterator idx;
    bool f= false;
    string s;
    while(getline(cin,s))
    {
             if(f)
             cout<<"\n";
             
    
             
              f=true;
              for(int i=0; i < s.length() ;i++)
              {
                  if(s[i] != 32 ) 
                 {
                      idx = find(map.begin(),map.end(),s[i]);
                      
                      if(idx != map.end())
                      {
                             idx--;
                            cout <<static_cast<char>(*idx);
                       }
                   }
                   else
                   cout<<" ";  
                      
              }
             
    }
    return (0);
}

Simple hints:
1. Don't use std::vector or something else for that problem. Just use static array.
2. Array must be filled such that you could simply write: cout << encode_table[ input_char ];

I was using texto = gets(), with texto being char[10000] and was getting wrong answer... after I switch it for c = getchar(), i got AC.

What does this mean?

Code: Select all

7961513  	10082  	WERTYU  	Accepted  	C++  	0.008  	2010-05-11 21:30:27
7961460 	10082 	WERTYU 		C++ 	0.000 	2010-05-11 20:54:31
7961442 	10082 	WERTYU 		C++ 	0.000 	2010-05-11 20:46:36

For the first 2 submissions there are no verdicts. And the mail I got has this:

Your submission with number 7961460 for the problem 10082 - WERTYU has failed with verdict .
Your submission with number 7961442 for the problem 10082 - WERTYU has failed with verdict .

It doesn't say WA, RTE, output limit exceeded, nothing. I had to make the variables global and then increase the array size to get it accepted.

May be a bug.

This simple problem is driving me mad .I have no idea what's wrong with that.!!
this is my code :
any ideas???
import java.util.Scanner;

class Main3 {
public static void main(String[] args) {
String prosseLine;
char prossChar;
char[] sequence = { '`', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'0', '-', '=', 'Q', 'W', 'E', 'R', 'T', 'Y', 'U', 'I', 'O',

';', 'Z', 'X', 'C', 'V', 'B', 'N', 'M', ',', '.', '/' };
Scanner scanner = new Scanner(System.in);

while (scanner.hasNext()) {
prosseLine = scanner.nextLine();
for (int i = 0; i < prosseLine.length(); i++) {
prossChar = prosseLine.charAt(i);
if (prossChar == 'A') {
System.out.print('A');
} else if (prossChar == 'Q') {
System.out.print('Q');
} else if (prossChar == 'Z') {
System.out.print('Z');
} else if (prossChar == '`') {
System.out.print('`');
} else if (prossChar == ' ') {
System.out.print(' ');
} else if (prossChar == 92) {
System.out.print(']');
} else if (prossChar == 39) {
System.out.print(';');
} else {
for (int j = 1; j < sequence.length; j++) {
if (prossChar == sequence[j]
&& (prossChar != 'A' || prossChar != 'Q' || prossChar != 'Z')) {
System.out.print(sequence[j - 1]);
continue;
}
}
}

System.out.println();

Is anyone getting AC on UVa and PE on PC with this problem?

Code: Select all

Removed after taking it to heart that AC on one judge is good enough.

SA,

I have got Wrong Answer in 10082 Problem.

I tested it and got right answers like that in Toolkit,
So i Hope any one can help me,

Here is my Code:
-------------------

import java.util.Scanner;

public class Main
{
public static void main(String[] args)
{
boolean bool;
String Output="";
char Chars[] = {'`','1','2','3','4','5','6','7','8','9','0','-','=','0','Q','W','E','R','T','Y','U','I','O','P','[',']','\\','A','S','D','F','G','H','J','K','L',';','\'','Z','X','C','V','B','N','M',',','.','/'};

Scanner in = new Scanner(System.in);
while(true)
{
String Input= in.nextLine();

for(int i=0;i<Input.length();i++)
{
bool = false;
if(Input.charAt(i) == 'A'||Input.charAt(i) == 'Z'||Input.charAt(i) == 'Q')
{

System.out.print(Input.charAt(i)); continue;}
for(int k=1;k<Chars.length;k++)
{
if(Input.charAt(i) == Chars[k])
{
System.out.print(Chars[k - 1]); bool=true; break;
}
}

if(!bool) System.out.print(Input.charAt(i));
}
System.out.println();
}
}
}

Thanks,

Exactly two line of code -

istreambuf_iterator<char> iit (cin.rdbuf());
transform(iit, istreambuf_iterator<char>() , ostream_iterator<char>(cout), Decipher);

Believe me this will get AC

Posted: **Fri Jan 11, 2013 1:09 pm**

I got WA before, but after i put that qwertyu[' '] = ' ', i got AC... so my mistake is just forget that space is space

Posted: **Mon Mar 02, 2015 6:29 pm**

I challenge everybody find where my answer is wrong ? if u find plz help me.

I got five times WA.

Code: Select all

#include<cstdio>
#include<iostream>
#include<map>
#include<string>
using namespace std;
map<char,char> k;
int main()
{
	int i;
    char key[]={'`','1','2','3','4','5','6','7','8','9','0','-','=','Q','W','E','R','T','Y','U','I','O','P','[',']','\\',
    'A','S','D','F','G','H','J','K','L',';','\'' , 'Z','X','C','V','B','N','M',',','.','/','\0'};
    for(i=1;key[i]!='\0';i++)
	{
		k[key[i]]=key[i-1];
	}
	key[' ']=' ';
    char s[10000];
    while(gets(s))
	{
		for(i=0;s[i]!='\0';i++)
			cout<<k[s[i]];
		cout<<endl;
	}
    return 0;
