Could we remove Trie.java from this PR? This PR is focused on adding the array rotation utility, but the Trie implementation seems unrelated to the main purpose of the change. Keeping it here makes the PR larger and also introduces additional code that doesn't have corresponding tests. I think it would be cleaner to move the Trie changes into a separate PR.

[mohithvardhan002]

What should happen when k is negative? In Java, % keeps the sign of the dividend, so a negative k can result in invalid indices during reverse(). Could we either normalize k to the range [0, n) or explicitly reject negative values, and add a test for this case?

[mohithvardhan002]

Could we also add a test for rotateLeft() when k is greater than the array length? The current test only covers this case for right rotation, while left rotation has separate logic.
