//after reversing just start comparing if at any time the value doesn't match it's not a palindrome, i.e. return false, else it's a palindrome and return true.
* Even phase: compare (0,1), (2,3), (4,5)... → no overlap → safe to parallelize * Odd phase: compare (1,2), (3,4), (5,6)... → no overlap → safe to parallelize ...
