## Instruction

```
All input files are under `/app`. Save your output file(s) under `/app/output`.

Using the beak depth data (bd_1975 and bd_2012) for G. scandens from 1975 and 2012, generate 10,000 bootstrap replicates of the mean for each year (set random seed to 42), compute the difference in mean beak depth between 2012 and 1975, and calculate a 95% confidence interval for this difference; save the results to "result.csv" following sample_result.csv with column names exactly "diff" and "conf", where "conf" is formatted as a string "[lower, upper]" with both bounds rounded to 8 decimal places.
