I have provided the correct test cases as a screenshot as well as the failed test cases. It says 0 out of 4 passed. The program must pass the test case when uploaded to Hypergrade.  Files data are down below: text1.txt StopAndSmellTheRoses.   text2.txt ATrueRebelYouAre!EveryoneWasImpressed.You'llDoWellToContinueInTheSameSpirit.
