The program receives an input text file with a restricted format$($Check the sample input file, sample.txt$)$ containing tens of multiple$-$choice questions$($assume N questions$)$ and the correct answer to each question. then the user determines how many booklets $($assume m$)$ with how many questions$($assume n$<=$N$)$ should be generated. As the output file, the program generates $2$ files for each booklet, one for the questions and one for the answer sheet. in the booklets, the order of the questions should be random, and the options should be randomly changed.
