minus-square@[email protected]linkfedilink11•edit-213 days agoBecause the abs(3) == 3 is true and that isn’t even. An even number of flips would be true and an odd number of flips would be false which works out. I was thinking a bitwise & or converting it to a string and testing if the right most character is 0, 2, 4, 6, 8 would be panic mode solutions too.
