I will use this thread to post video editorials about the long challenges, once the contest is over.
Video for NOCHANGE (HINDI) (Recorded while solving, but could not add due to editing)
Premiere Link for CHEFRAIL (To be live after contest gets over)
Premiere Link for EXPCH (To be live after contest gets over)
Every beginner must start with long challenges for a tremendous growth.
Update : Added an introduction to the contest.
(Please do not discuss strategies until the contest is not over)
