For this closed lab, you will be debugging two defective implementations of the Swap_Substring operation, called Buggy_1.cpp and Buggy_2.cpp. The source files will not be made available until closed lab. In the meantime, the tester asked if the instructor would pass along test cases revealing defects in Buggy_1.cpp and Buggy_2.cpp.
You should study the test cases and convince yourself that
they reveal defects. Think about how you might approach the debugging
task. Feel free to get organized with a partner, and there is nothing to
turn in for this homework.
