Pull request overview
This PR adds visual feedback for answer correctness by applying background colors to response boxes. The color ranges from red (incorrect) to green (correct) based on a similarity metric between the user's answer tree and the solution tree.
- Uncommented and activated the correctness evaluation logic that calculates similarity between expression trees
- Implemented the
evaluateCorrectnessfunction that compares two expression trees using a formula based on identical nodes and tree size differences - Applied background colors to both response boxes and color boxes in the answer history

…on (#12) Addresses question on PR #9 about helper function refactoring to reduce code duplication in response colour coding. ## Changes - Added `getColourString()` helper function to encapsulate RGB string formatting - Extracted repeated color string construction (8 occurrences) into single variable
This loop continues until the DFS of one of the trees is complete. The use of a for loop here was harder to read, so I replaced it with a more obvious while loop.
