Find XOR of all numbers in a given range
... ^ 3 ^ 4 .. ^ b
b is greater than a, so just by safely dropping in a few extra brackets (which we can because it's associative), we can also say this:
f(b) = ( 0 ^ 1 ^ 2 ^ 3 ^ 4 .. ^ (a-1) ) ^ (a ^ a+1 ^ a+2 .. ^ b)
Which simplifies to:
f(b) = f(a-1) ^ (a ^ a+1 ^ a+2 .. ^ b)
f(b) = f(a-...
