[@ogbuddha7835]

Aapne insert krne ka 2 method bataya 1 - umap["prince"] =1; 2 - umap.insert(make_pair) . But last mein umapped wale part mein jab Aapne mapped[key] ++ kiya to ye element insert krne ka ek naya tarika hai jisse ki itr->second part Mein ads hota hai no of times repeated

[@udaytewary3809]

Isse element tb hi insert hoga agar wo map me pehle se present na ho agar present haa pehle se to uski frequency sirf badhegi

[@ogbuddha7835]

[@HelloWorldbyprince]

Some sort of kah sakte ho aap

[@HarshMishra-cp7tj]

Epic Way of Teaching

[@kushalshukla444]

bro ye unorded map main agar hum value na de to vo by default 1 store krdeta hai kya. but its not the case with map right?

[@HelloWorldbyprince]

Nahi i guess map v tum kar sakte ho Ek baar try karke dekhna to Error aa rha hai kya ?

[@kushalshukla444]

Okay

[@deezero7103]

Mast

[@HelloWorldbyprince]

Super

[@sandalagrawal8587]

It was a great video bhaiya! Greatly explained! Thank you so much. Also is it possible in unordered_maps to search with the help of values. Like if we don't know the key but the value, how will we search!

[@HelloWorldbyprince]

Thanks Sandal, nahi na, because map ka matlab hi hota hai pair of ( key, values ) and key se hi humlog search kar sakte hia

[@AnandKumar-oo2oy]

Bhaiya ek doubt tha Kb dot Or kb arrow ko use krte hai unordered maping me. Please bhaiya replay.

[@HelloWorldbyprince]

Nice buddy 😌

[@paraskumar693]

which hashing technique is used in unordered map

[@HelloWorldbyprince]

its inbuilt of c++

[@prakhar266]

completed

[@HelloWorldbyprince]

Thanks a ton

[@BMEFaisal_khan]

Bhai.. Or video aapne nhi btaya.. Like linear probing, quadratic probing?
