Problem statement

For every nonempty prefix length, reverse that prefix and leave the rest unchanged. Also do the same for every nonempty suffix length.

Return the lexicographically smallest string among all produced results.

Function

smallestEndReversal(text: String) → String

Examples

Example 1

text = "cba"return = "abc"

Reversing the entire prefix yields abc.

Example 2

text = "abcd"return = "abcd"

A length-one reversal leaves the already smallest string unchanged.

Constraints

1 <= text.length <= 2000
text contains lowercase English letters.
