[SOLVED] Property between XorSum and Sum of segment

Правка en3, от prudent, 2018-06-27 13:07:14

Question is solved, please ignore this post

Why if xor sum of segment is equal to sum of segment, this condition is also satisfied for all subsegments of original segment?
I know that it's true when all bits in numbers are unique, but is it the only case when it's true, and if it is, then why?

Теги xorsum, sum, xor properties, need explanation
