It all depends on your interest and your future plans. if you want to become an engineer or go into the science or research field, I would highly recommend you to go with Computer Science as nowadays no matter in which field you are, at some point, you'll have to rely on computers and write a few lines of code, and at that time this subject will help a lot.

If you want to go in the spiritual field or want to pursue Sanskrit further, like do a PhD in Sanskrit, then you should definitely go for it. All the best!
