Counting Cycles

Given a graph as .. an adjacency matrix, calculate the total number of distinct simple cycles.
Remember that A - B - C - A is not the same as A - C - B - A, and that A - B - A is the same as B - A - B.

Input

.. Same as before.
N ≤ 10.

Output

The number of distinct simple cycles of any length.

Sample Input

3
0 1 0
0 0 1
1 0 0

Sample Output

1

I am getting this error and I can't find the cause of it. The standard error message doesn't say much: "terminate called aft".

Test case #5: RE (signal 6: SIGABRT) [0.192s, 2888K] (0/10) (Details)

What kind of errors/bugs are related to a RE?

Thanks for the link, but I have read it many times. It wasn't helpful this time.

If you're getting a terminate when you don't expect it, it's probably one of two things: bad_alloc (more likely) or out_of_range.

bad_alloc is thrown if, for example, you try to create a vector of 10 million ints. You don't have 40M of memory available to you, so it'll fail.

out_of_range can be thrown if you're trying to get an invalid substring, or if you use a range-checking accessor, like Vector::at().

(In your case, it's a bad_alloc.)
