In the program dont use buffer reader, file reader, io exception, hashmap, map or scanner and please modify or create a new program ASAP BECAUSE hypergrade does not like the program down below and the progran does not pass all the test cases when I upload it to hypergrade. I have provided the correct test case as well as the failed test case as a screenshot. It must pass all the test cases because it says 0 out of 2 passed when I upload it to Hypergrade. The program must pass the test case when uploaded to Hypergrade. Thank you
