Aap konse college mai hai

Nice ! Keep it up 👍🏻✨👏🏻👏🏻

Amazing explanation ! ❤️👍🏻✨

Bro if array is 0 , 6 , 7 for 2nd question what should be the output? YES or NO

bro in last question u didn't explain that how u generated that formula

Nice

Kya aap contest ke que bhi karayege

Bhaiyaa aap ki rating kya hai codechef mai

Bhaiya kuch tips do na 😋

Bhaiya aap toh itne hushaar ho , aap toh Google mai honge na 🤔🤗

Very nice !! Explanation keep it up ❤️👏🏻👏🏻👍🏻

Nice explanation

Nice explanation

Nice explanation

dark mode

Bhai, contest ko mazaak kyun banake rakha hai, ye rating talented logo ko apna capabilities dikhane ka ek jariya hai, please chhod de

bro how to visualize python code?

Hlo bro

bahut kharab explanation

Bhai tujhse nahi hoga rehne de 😂

Amazing explanation!... Thank you:)

i dont get this logic....please explain bro
