+}
+```
+
+In this example, the minimum memory is 16 GB. The memory will increase depending on the size of `input_file`, and the number of attempts (`task.attempt`). Note: `input_file.size()` must be converted to bytes in order to perform calculations (e.g., to prevent `Unknown method invocation div on Long type` errors).
