To nayimsust...
Your input array is too large for this problem.
Problem says the input message will be in 80 characters.
You took char a[1000000].

Please try this case:
* means a space
My AC code produce:
But your code just produce 2 blank lines.
Also, there are some problems in decoding.
your code cannot handle the number bigger than 99.
Such as:
My AC code produce:
However, your code did nothing but output 2 blank line.
I think you should use backtracking when you are decoding.
Hope that you can find the bug.

I tried a lot of test cases! All possibilities i know, but it gives me WA since 2 years! Can some one find the bug?
Code: Select all
#include <iostream>
#include <string>
#include <sstream>
#include <algorithm>
using namespace std;
int main() {
int i, a, size;
string line, inv;
while (getline(cin, line)) {
size = line.size();
if(size==0)
{
cout<<endl;
continue;
}
if (line[0] < '0' || line[0] > '9') {
for (i = size - 1; i >= 0; i--) {
ostringstream osd;
osd << (int) line[i];
inv = osd.str();
reverse(inv.begin(), inv.end());
cout << inv;
}
} else {
for (i = size - 1; i >= 0; i--) {
ostringstream ose;
if (line[i] != '1') {
a = (line[i - 1] - 48)*10 + line[i] - 48;
i--;
} else {
a = (line[i - 2] - 48)*100 + (line[i - 1] - 48)*10 + line[i] - 48;
i = i - 2;
}
ose << a;
inv = ose.str();
reverse(inv.begin(), inv.end());
istringstream iss(inv);
iss >> a;
switch (a) {
case 7: cout << 'F';
break;
case 8: cout << 'P';
break;
case 9: cout << 'Z';
break;
case 1: cout << 'd';
break;
case 11: cout << 'o';
break;
case 12: cout << 'x';
break;
default: cout << (char) a;
break;
}
}
}
cout << endl;
}
return 0;
}

Maybe you should try to write a bit more clear and concise code? This table looks very suspicious to me, I wouldn't be surprised if you had a bug in there:
Code: Select all
switch (a) {
case 7: cout << 'F';
break;
case 8: cout << 'P';
break;
case 9: cout << 'Z';
break;
case 1: cout << 'd';
break;
case 11: cout << 'o';
break;
case 12: cout << 'x';
break;
default: cout << (char) a;
break;
}
Just rewrite that part of code from scratch in a more natural way, without any hard-coded tables like that.

if(len-1>=0)
{
temp = temp*10 + ((int)msg[len-1]-'0');
printf("%c",temp);
len-=2;
if(len==0)
{
temp = (int)msg[len]-'0';
printf("%c",temp);
len--;
}
}
else if(len==1)

You can assume a spy's message is at most 80 characters long, and it includes all the upper and lowercase letters of the alphabet plus the space, and any of the following characters:
! , . : ; ?
this is given in problem statement.
input may have other characters like " - "............. taking ascii 32 to 122 in account RE might be solved.....

This problem is lying. I had my input array at 100 before and it gave me RTE. I increased it to 1000 and it worked. Stupid.

I removed my post after AC.
But I provide some critical test cases for you. Just check these and get AC.
