Midterm Exam 2

Specification

For Mid2, a sample compile command on JOJ for ex1 is gcc -Wall -Wextra -Wpedantic -std=c11 -o ex1 ./ex1.c.
During the exam, you may submit your code on JOJ to see whether it compiles correctly. There will not be limits for the submission. Note that it has nothing to do with your final grade since we will only give you the public testcases during the exam.
Mid2 is open book and open Internet.
JOJ Submission will be closed on 4:15pm. If you fail to submit your code on JOJ, please do the submission on Canvas.
Note that the ending time for the exam is 3:50pm, and the due for the submission is 4pm. JOJ will open until 4:15pm to handle extreme cases.

(official updates for the exercises in mid2 will be placed here)
