A code may or may not be preceded by a 0 in the encrypted string
but not can be ended with a code make of zeros.
Try this I/O:


Code: Select all

a 1
b 10

Code: Select all

Case #1
Note that the solution "a" is wrong because ends with a code of zeros.

215 WA?? (need solution for this input)

Hello! I've received WA many times. :cry: :cry: Anyone could write the correct output for this input, please. The first case is problematic. Obviosly the result is 0, but it involucrates the same cell. Which is the correct interpretation? 1 1 A0-A0 4 4 A1-A2+A3 A2 A3 6+B1 A3 5+7-8 6+A3-A2 B2+7-15+B1...

Code: Select all

while(i<l && s[i]==old[i]) i++; //<<-- problematic line! 
a[ old[i]-'A' ][ s[i]-'A' ] = 1; 
If you exit the while because i=l; then old or s has the value '\0'.
When you try to access to a[ old-'A' ][ s-'A' ] you get RE.
In the second code you verify that old!='\0' and s!='\0'

I received WA many times. I don't know the reason, but finally I read numbers as doubles and got AC.

I received many times WA because I use to read scanf ("%s",a) to get the names. This have a problem, when it finds a space, it stops reading.
Finally I got AC usint scanf ("%[^\n]");

Be carefully when if you declare an array to save the numbers. The size of this array must be at least 300!! (because there are a maximum of 100 characters).
I made this error and get WA to many times. :D
