Find XOR of all numbers in a given range
... binary representation and then the decimal result and its relation to its index (a) into the XOR list. This happens because all the upper bits cancel and the lowest two bits cycle every 4. So, that's how to arrive at that little lookup table.
Now, consider for a general range of [a,b]. We can use...
