One beautiful property of XOR (symbol : \(\oplus\)) is that for any integer \(x\), we have \(x \oplus x = 0\). Using this property, Chris came up with an algorithm that check if a list \(L\) is palindromic.

Certainly, this function is restricted to lists that contain only numbers. What is the domain of the numbers in the list such that this function is applicable without error?
Details and Assumptions
a ^ b
returns \(a\oplus b\).L
is palindromic if L
remains the same after applying L.reverse()
.L[1]
, second last element is L[2]
and so on.Problem Loading...
