11278 - One-Handed Typist

[Robert Gerbicz]

This is a very easy rated problem using my rating, however they give only a dirty picture and on it some of the letters are unvisible, I've tried also the pdf file and done magnification but I've got only WA. I don't know why they haven't provided as a text file the old and the new layout. This means 2 wrong problems on the contest because without it the next problem is also wrong. Congratulations to the problemsetter(s).

Can somebody give me the correct layout of the old and the new keyboard?
Thanks in advance.

These are the strings I have in my AC code (I just do a linear search in each string for every character in the input).

char *l=
"`1234567890-=\
qwertyuiop[]\\\
asdfghjkl;'\
zxcvbnm,./";
char *r=
"`123qjlmfp/[]\
456.orsuyb;=\\\
789aehtdck-\
0zx,inwvg'";
char *L=
"~!@#$%^&*()_+\
QWERTYUIOP{}|\
ASDFGHJKL:\"\
ZXCVBNM<>?";
char *R=
"~!@#QJLMFP?{}\
$%^>ORSUYB:+|\
&*(AEHTDCK_\
)ZX<INWVG\"";

I appologize to everyone because of the quality of those images. I extracted them from the original pdf files, so it got messy, but I thought they were readable. Apparently not.

Robert, after you sent me that email, I asked them to post the link to the original pdf files, which they did. It is easy to miss, because that page does not get refreshed automatically.

The problem with A and B was mainly because the new system somehow added a blank line to all input files. Which only mattered for A and B. And for a bunch of old problems - I was told they finally found the bug, at least something good came out of it.

Again, it was all my fault, nothing to do with the problem setter. Well if he was not a Mac person I could've used his original files...

Thanks. Now I got AC.
But WA for the next similar (easy) problem: "KEYBOARD COMPARISON", correct output for the sample input tests, I'm using here small eps to avoid precision problems ( because the answer can be an integer ).

Ps. Forget me, I've solved "keyboard comparison".

why WA


Here's my code

#include<iostream.h>
#include<stdio.h>
int main()
{
int i, j, m=39, n=34, p=32;
char a[]={"`1234567890-=\qwertyuiop[]asdfghjkl;'zxcvbnm,./"};
char c[]={"`123qjlmfp/[]456.orsuyb;=\789aehtdck-0zx,inwvg'"};
char b[]={"~!@#$%^&*()_+|QWERTYUIOP{}ASDFGHJKL:ZXCVBNM<>"};
char d[]={"~!@#QJLMFP?{}$%^>ORSUYB:+|&*(AEHTDCK)ZX<INWVG"};
char s[100];
while(gets(s))
{
for(i=0; s!='\0'; i++)
{
if(s==95)
cout<<(char)n;
else if(s==34)
cout<<"?";
else if(s==32)
cout<<(char)p;
else{
for(j=0; j<46; j++)
if(s==a[j])
cout<<c[j];
for(j=0; j<46; j++)
if(s==b[j])
cout<<d[j];
}
}
cout<<"\n";
}
return 0;
}

"%" is a specifier character for printf, so you can't print "%" directly. (But my Borland5.5 compiler prints it).
Change line

Code: Select all

else if(str[i]=='W')
             printf("%");

It must be

Code: Select all

else if(str[i]=='W')
             printf("%%");

Or

Code: Select all

else if(str[i]=='W')
             putchar('%');
