Time Complexity

$O(n)$

Space Complexity

$O(n)$ words

(At the very least it pre-processes and stores the string and the reverse of the string, requiring O(n) space. Space usage is bounded from above by runtime, so at most O(n) space is used.)

Description

Approximate?

Exact

Randomized?

No, deterministic
