Hello,
When you had started this channel and I had seen your first video. At that time I was thinking you are outstanding.your explanation way and content outstanding. I know you will hit the 10M Subscribers.

[sinigeorge]

Hi Sir, Thanks for always updating the playlist!

kabhi kabhi mera dil me khayal aata ha agar Gate Smashers nhi hota to mera kya banta

[shashanksharma]

one of the best faculty in youtube platform

[duadua]

Best teacher in world sir g ap sa request hy mcq k sb subject k lecturer upload kr dya plzzzz

[anitajain]

Hello Sir,
Thankyou for explaining all topics in wonderful way, it helps me alot in my bachelor's degree. I need your guidance in my career .so how can I ask?

[saurabhdubey]

Even i%2 can be changed to i=i+2 in for loop
It's a strength reduction and loop invariant I think

[lalitkumar]

Hi sir, can we shift condition statement from High frequency to low frequency region like u shift if(i%2)? ....bcos next x and y statements execution depends on this condition and in case if we shift it then j loop will not run for each value of i like as usual it was before shifting.

[UKAFSHOHAIL]

Thankyou sir for giving this wonderful information

[PranjayVats]

In the first loop cant we increment the loop variable 'i' by 2 every time rather than by 1 as we can see we are doing further operations only when i%2 is true and there is no else part. This will also optimize our code as our loop will excecute for N/2 times. But can anyone tell me that if we do that then what kind of optimization would it be?

[pateldarsh]

Khadda hu aaj bhi vahi jo tera intezaar you broke my heart :(

[akarshjain]

Sir ji plz do not forget to upload videos on new topics please sir

[sukh-e]

Sir please cover the new topic of compiler design for gate 2021

[grovestreet]

can we optimize this code like this ?? int total_sum=n*(n-1)/2;
int u=n/2-1;
int num=4*total_sum;

int x=num + 5*u*(u+1);;
int y=7*(n-1)+ num;

cout<<x<<y<<endl;

[Moglikidunia]

Sir kindly en k handouts b share kia krein .

[HassanRaza-rl]

sir g app kbhi pakistan b aaeinn please😍😍🙃🙃

[entire_life]

Sir, Scientific Techanical assistance paper solution!?

[lishaanjum]

Started watching the whole playlist before 1 hour of final exam...😢

[umernoor]

I couldn't understand the option ( C ) Scope of strength reduction.
