Samaysya-purti

Samaysya-purti (Devanagari : समस्या-पूर्ति / literally satisfaction of a problem) is a class of Indian literature, specially popular in Sanskrit, but also known in other languages.
In Samasya-purti, the problem is posed by providing part of a metrical composition. The challenge is to compose the rest of the composition.
Some scholars have taken the last line of each verse of Kalidasa's "Meghadutam" as the samasya, and have composed the rest.
