About 재생시간 계산기 (메가스터디)

Korean students take Internet lectures according to their plans. The site with the highest number of students is megasudy. However, this site offers double speed, but it does not tell you the length of the video that varies due to the double speed, so students have to use a calculator to calculate it themselves. To make it more convenient, I created a program that automatically shows the time when you go to the megasudy site. This makes it easier for students to write study plans.
