Hi,

.. wrote:Cache up to 8 steps only can make you use less memory.

this meaning that cache up 8 steps, and not 16, solve this problem?

thants in advance...

You can cache upto 9 ar 10 steps. But 8 is better.

Hi,

thanks Jan.
How can I differentiate the states? Can I use something

Code: Select all

   x=0;
   for(i=1;i<=MAX;i++) x+=i*state[i-1];

??? This is correct?
thanks in advance.

I dont know what is the content of state[]. So, can't verify whether it's correct or not.

P.S. You can use hashing to save the states.

hello, i use bfs, first from the target to serch depth=7, and then, search from the beginning.
during the second bfs, everytime i check whether the state has appeared.
at the same time, i use hash.
so, why i even can't pass the sample input.
could someone help me ? thank in advance?

this is my code,help me!
