[@manjoydas1455]

Ans for qus 3 is perhaps wrong here. It should be (a+ab)^+ since the regex in the video is also accepting epsilon which is not desired. Education 4u must post the correct answers in comment box if there is any mistake in the video.

[@mufeenashahul4637]

Please write, correct ans, please

[@sairamgreeneye9096]

I have watched some of the lectures those were very understandable thank you ma'am

[@deepakdeshmukh2013]

(a+ϵ).(b+ba)*. Mam How to write this regular expression to simple English.

[@newspresentersacdemybd8786]

If the R:E: for number 3 is= (a+ba)* then whether it would be wright or wrong?? Plz let me know as soon as you can.

[@nithinjohnson2318]

No, that would be wrong. The question says, the language should start with 'a'.

[@DirasatLanguage]

Great lesson

[@beingyourself4553]

third question may be wrong 3:19 ,a(ab)*

[@8LuCiia8]

Amazing. Thank you!

[@shivendratripathi8306]

In question 3 it should be + instead of a * as we have start a string from a and empty string is not accepted na?

[@archanamahanty8561]

Pls can you find the set of strings for the regular expression (aa+b)*and (bb+a)* And also (aa+b)*(bb+a)*.

[@ElifArslan-l9g]

Thqu bhanu mam

[@harinisridharan5880]

In the 5th example why can't we write it as (10)*

[@deblinachakraborty1232]

its because other combination like 100 or 110 will not be accepted by (10)*

[@newspresentersacdemybd8786]

Bro, (10)* is totally wrong right here, suppose 10101010, which is a RE of (10)*, then have a look ,there are 01 string inside.

[@mufeenashahul4637]

Miss, in 3 rd exmp, epsilon not accept, any One know correct ans

[@muneebnadeemabbassi3295]

a(a+ba+ab)*

[@prashantrajput4881]

(0+1)*(11+10+00) Ma'am example no.5th ka R.E esa bhi likhh sktaa ha

[@newspresentersacdemybd8786]

I think no bro, 011 is a valid expression for you RE and here 01 string is remaining!
