Thank you sir your teaching is amazing ❤️

[@chitvangarg9684]

hello bhaiya,i am following your all gate subject series from last 2 months and the explanation of topic are very simple and easy to grab but i have big problem with your series is that when you make a frame in students mind who is new to the topic by syllabus overview and they could not find the videos arrange accordingly then that leads to choosing channels that are providing structure videos...like in series of toc video number 46 you introduce to CFL AND CFG but i could not find videos arranged according to that videos...this is my opinion feedback else you are providing best content.

Sir isi ko simplification of cfg bolte h kya?

[@world_life_call]

Sir, kindly remove the null productions and find the final productions for the given problem
S → XYX
X → 0X | ε
Y → 1Y | ε

[@siddharthmagadum16]

S->XYX | XX | XY | YX | X | Y | ε
This may be right as we have replaced each variable with ε .
UPD:
Anyone respond to this, as am not sure ....

[@368ashish]

X -> XYX|Y|XX
X-> 0X|0
Y->1Y|1
