This is a simple exchange verifier for a small exchange that supports only one feature, the limit order.
To run the application, you can use the following command:
./gradlew build
Once the application is built, you can run it by using the following command:
java -jar build/libs/simple-exchange-1.0-SNAPSHOT.jar
The application will read the input from the standard input and print the output to the standard output.
To run the unit tests, you can use the following command:
./gradlew test
Here are some examples of how to use the application:
cat src/main/resources/test1.txt | java -jar build/libs/simple-exchange-1.0-SNAPSHOT.jar
50,000 99 | 100 500
25,500 98 | 100 10,000
| 103 100
| 105 20,000
cat src/main/resources/test2.txt | java -jar build/libs/simple-exchange-1.0-SNAPSHOT.jar
trade 10006,10001,100,500
trade 10006,10002,100,10000
trade 10006,10004,103,100
trade 10006,10005,105,5400
50,000 99 | 105 14,600
25,500 98 |
And here's how to get MD5 of the output
cat src/main/resources/test1.txt | java -jar build/libs/simple-exchange-1.0-SNAPSHOT.jar | md5sum
