• @prog_SAHIL - I think the key trick is to get the right answer in quickly, and then embellish it with images/formatting for clarity. The perfect is the enemy of the good. – Phylyp Jan 18 '18 at 12:01
• @prog_SAHIL Sorry (not really!) I have added some ascii art now. – Jaap Scherphuis Jan 18 '18 at 12:07
