I would like to add a small correction here : it's not that if any symbol appears on the right side, then it's not useless. We must also check if it is reachable from the start symbol. If it is not at all reachable from the start symbol, it should also be useless symbol.

mam so i cudnt understand where should be the non terminal and terminal symbols shd be,,,,right or left??

Thank u so much mam👍

Thank you

Tq so much mam

You should remove B-ab also because non terminal tends to non terminal otherwise non terminal tends to terminal... In above rule it gives nonterminal tends to terminal. terminal hence u should remove that also

very nice && helpful

Thanks

🙏🏻🙏🏻

What if A -> aA/a in the example ? 5:10

Then it will be considered and will not be removed because it has a terminal

Thank you very much mam

I think here after I pay my college fees instead of my institute

aaT will also remove... Unless it will produce infinite number of aaT

Yes

If T(start symbol) is not present in right hand side then T is an useless symbol or not..?

lmaoo, question shuru hone se pehle hi khatam krdiya xDDDDDDDDDDDD

I think 'ab' should not be removed ..because 'ab' generates a meaningful string and not a wastage of memory because it can be used in 'aaT' as 'aaab' .

Some mistake: T --> abA A --> aA --> abaA --> abaaA --> abaaaA
