The original output for the test sequence (as posted by pperm) is correct. The last two tests are identical except for the lenght of the 0/1 sequence, which the third question in the 5th test violates, thus giving 2 as the correct answer. I don't know if this is an issue tested by The Judge though ^^

5
5 6 odd
7 8 odd
1 6 even
1 4 odd
7 8 even

for the above input I don't understand why the output should be 4. if 5 6 is odd and 1 6 is even, 1 4 is even, isn't it?

There is nobody wrong ...
Because the problem in "18 26 odd" at the fifth test is that 26>20(the length of the sequence) ...
But the description of the problem doesn't say anything about this situation , and also there no data like this ...
So I doubt that we can use the length of the sequence to do what -_-!!!

Re: Some tests :)
No, 1 4 must be odd, because 1 4 + 5 6 = 1 6 or in other words odd + odd = even :)

correct answer for the test
3
3
1 1 odd
3 3 odd
1 3 odd

is 0, because interval with zero length contains 0 (even) ones :)

Yes, it is just something strange.
My program passes all the mentioned tests perfectly.
I took in the accounts every remarks mentioned in this forum and still I get WA1.

I'm in the same boat. all tests listed here are passing. but still got the WA1. anyone knows how can i get hold of the tests OJ is using? or at least get the feedbacks on the specific failing test case?

Altoids, maybe we should try this test (answer -> 4):
12
6
1 2 even
1 1 even
3 4 odd
5 6 even
1 6 even
7 10 odd
-1

This is not correct. The range from 1 to 1 includes one digit at position 1.
