Nope. If the solution is 'ab' then of course 'ba' is a solution, too. right?

pls help WA. I didn't find my bug in my code.every time i got WA here is my code
Code: Select all
At last Acc
Re: 10252  Common Permutation
what is meant hear by "permutation" && "subsequence"??Given two strings of lowercase letters, a and b, print the longest string x of lowercase letters such that there is a permutation of x that is a subsequence of a and there is a permutation of x that is a subsequence of
i am totally in dark
please help
lives for eternity......
Re: 10252  Common Permutation
Subsequence: Suppose you are given two strings A and B. B will be said the subsequence of A, if you can make B from A by deleting some (or none) characters.
Permutation: Suppose you are given two strings A and B. B will be said the permutation of A, if you can make B from A by rearranging some (or none) characters.
So, 'abc' is a subsequence of 'adbfc' and 'aabc' is a permutation of 'caba'.

Re: 10252  Common Permutation
Hi, I just got AC without caring about such cases with uppercases like aaAAAaaa or whatever and there is no such thing. And yes, LCD can be used, I used it but I gonna change it for the simpler alg now!!
I read too many posters for nothing

Remove your code after AC
Re: 10252  Common Permutation
I got AC!
I read just letters a..z and <space>
And ignore the last output, I dont know why, but work. =/

Re: 10252  Common Permutation
After suffering a lot, finally i got Ac
The only problem is take input by gets() rather than scanf()
Hope it will work !

Re: 10252  Common Permutation
My problem is rather simple. I used the print_LCS from the cormen book:
and implemented in 2 ways:
recursive:
and iterative:
The recursive is giving AC, but iterative is giving WA. While calling I pass the same parameters and for len pass the maximum length. The test cases passes for both implementations. Isn't this peculiar that it still gives WA for iterative one?
Code: Select all
PRINTLCS(b, X, i, j )
1 if i = 0 or j = 0
2 then return
3 if b[i, j ] = “&”
4 then PRINTLCS(b, X, i ? 1, j ? 1)
5 print xi
6 elseif b[i, j ] = “?”
7 then PRINTLCS(b, X, i ? 1, j )
8 else PRINTLCS(b, X, i, j ? 1)
recursive:
Code: Select all
void print(char a[], int i, int j)
{
if (i == 0  j == 0)
{
return;
}
if (op[i][j] == 3)
{
print(a, i1,j1);
printf("%c", a[i1]);
}
else if (op[i][j] == 1)
{
print(a, i1,j);
}
else
{
print(a, i,j1);
}
}
Code: Select all
void print(char a[], int i, int j, int len)
{
char pr[MAX];
int k = len1;
while ((i != 0) && (j != 0))
{
if (op[i][j] == 3)
{
i,j;
pr[k] = a[i];
k;
}
else if (op[i][j] == 1)
{
i;
}
else
{
j;
}
}
pr[len] = '\0';
printf("%s", pr);
}
