AI Analysis

1. Key Issues: Attempt 1 had a syntax error (missing variable declaration). Early attempts contained loop logic errors (incrementing instead of decrementing) and array bounds issues. Specifically, the swap-search loop used i++ and the reversal started at the pivot rather than the suffix.
2. Evolution: The code improved by correcting variable scopes, fixing the search direction for the successor element, and adjusting the reverseArr indices to correctly target only the suffix.
