lab-exam-D105-106-1230 had a few bugs:

*q1: the example in the pdf, and in .h file the comments had ["*", "**", "***", ... , "****....*"], while the pdf and the test cases said required the first string to be the empty string: ["", "*", "**", "***", ... , "****....*"]

*q2: there were inconsistent instructions/example whether the output should be f(1)+f(2)+...f(n) or f(0)+f(1)+...f(n-1).


For grading we will accept both options.
