Bhaiiia u really know how to make shorts🤩

[@sagnikmitra710]

Bhaiya apke shorts videos boht interesting hota hai❤️❤️

[@AmitMaurya-vo4lj]

Thank you bhaiya ❤

[@elemento8763]

Awesome Short Video, once again Sir

[@justworkfine321]

Why 6?

[@yashwantpradhan]

Because the minimum negative value is -6. And the remaining negative values are greater than -6(like -4). So, if we add 6 to each one of them, then all the values will be positive.( Ex- -6+6=0, -4+6=2). @@justworkfine321

Nice video bro 👍👍

[@bhavyamathur211]

Well adding a positive of the minimum number is a bad idea. You can design a hash function instead or use a previously defined constant time hash function.

Hey @luv bro can you make a video and hands on for maps..plz beginners need it!!

[@iamluv]

tomorrow i am posting it. as part of my competitive programming course its the next thing in the course. Course playlist link is in description

[@narayanipandey4319]

Aur agar no. ki range (-N/2) to +(N/2) ho where N is maximum limit storage of int data type, tb fir kaise hashing karenge

🙏🏻 🙏🏻Sir, aap padhate waqt highlight krne ke liye konsa softwate use krte ho (jo laser jaisa dikhta hai phir apne aap gayab ho jata hai) 🙏🏻🙏🏻

[@anjalipatel3786]

Why we have to add only 6?

[@mobtricks257]

Brother c+ par bhi bana video full cross

[@iamluv]

Bhai bana hua hai.. course ko jo link diya hai usme phle10-11 videos pura c++ pe hi hai.

[@Sarkar.editsz]

Waah

[@dattawarade]

Negetive number ko absolute value directly concert nahi kr sakte kya.

[@mohan_792]

nhi bro, agar voh positive number bhi already array mai hua toh count galat ho jaayega.

[@Live-hh6li]

Crisp like papad

[@sharansunil4589]

How long will this course continue bro. By which episode will we have full expertise over CP

[@iamluv]

Basics should be covered by around episode 50. i guess maybe, for advanced there is no end i feel, there are just so many topic i could discuss but i will see what i would discuss and what i wouldnt.

[@darshantawte7435]

you can't become an expert in CP until you solve problems that too in contest. There is no point in just learning and not solving problems.

[@ru2979]

ek inssaan ne pucha hai 😂 🤣😂 lit bhai

[@himanshusahu3259]

Bhai ek question hai Main difference between class template and function template????? Please ans🙏

[@deepanshumishra4568]

Template class me tum ek class k bahut saare member function ko implement krke use krte ho apne program me But ek template function me tum sirf ek hi function ko use kr sktey ho. Class ka main purpose hota h bahut saare functions ko group krna, isliye hum template class kya use krtey h Or template function ka use tb krtey h jb ek hi operation performe krna ho

[@himanshusahu3259]

@@deepanshumishra4568 Thanks bro

[@omprasadrathod3600]

What if our array element is like -14 then if we add 6 in this then index is -8 then how could be possible to store at this index🤔

[@texz1359]

I know I am late but if the lowest negative number is mentioned I mean if range of array is from -M to +N where m and n are any number then just add M to every element that is to be added to the array and when giving the answer just subtract it. cout

[@adheeshpatairiya7353]

how to hash when the values of array exceeds 1e5 ? as integer max can be up to 1e9. Any Optimized method?

[@iamluv]

you have to use an implementation of a hash table, in c++ you can use maps or unordered maps

[@sahilbafna4970]

What if the value is INT_MAX

[@iamluv]

use stl

[@scaryme4662]

thambnel alag alag dalo brooooo

Hello sir can you help me

[@udaymishra5916]

Ye abhi bhi clear nhi hua sir ji
