thank you so much

[@Ahmed_Salah00]

bro I'm speechless! perfect!!

[@nikoo28]

Thank you so much 😀

[@rajakabdul6407]

Hae bro Can u explain What is Math.abs(i)

[@nikoo28]

it gets the absolute value. Example: Math.abs(-1) = 1 Math.abs(1) = 1

[@deepika8401]

I am able to solve problems because of you

[@vikrantkambli9265]

your explanation is crystal clear..thank you so much bro..

[@nikoo28]

So nice of you

[@BabyKrishna01]

Concept is clear with the video, please explain the program itself as well, why you are taking int c array or like thi

[@nikoo28]

the solution explains why we need the array. :) do you have a specific doubt? i can help

[@Philthyyy]

Very detailed explanation. Thank you for your time and insight.

[@maheshguttedar3620]

What an amazing video 🥰

[@92akky]

Nice explanation

[@nikoo28]

Thanks and welcome

[@rmukeshverma8724]

int n1{s1.size()}; int n2{s2.size()}; int result{}; vector sr1(26); vector sr2(26); for(int i=0; i < n1; ++i) { sr1[abs('a'-s1[i])] +=1; } for(int i=0; i < n2; ++i) { sr2[abs('a'-s2[i])] +=1; } for(int i = 0; i < 26; ++i) { result += abs(sr2[i]-sr1[i]); } return result; why it's incorrect?

Great video

excellent thank you :)

[@taherkp7321]

Hi. Just a question here, why are doing (s1.char(i) - 'a' ) here? what is the significance of 'a'. Thanks

[@nikoo28]

We want to index each character in alphabet. So ‘a’ = 0, ‘b’ = 1, ‘c’ = 2, ‘d’ = 3…and so on. With this statement we calculate this index. If charAt(i) is ‘a’ then we will get ‘a’ - ‘a’ = 0. This position is now used in array. If charAt(i) = ‘k’. Then ‘k’ - ‘a’ = 10 We get position 10 of array. Does this clear your doubt?

[@taherkp7321]

@@nikoo28 Yes.. Thanks

[@Grammar-EN]

bro in which language u explained

[@nikoo28]

this is in JAVA

[@pratyakshamaheshwari8269]

int makeAnagram(string a, string b) { int *c = new int(26); for(int i=0;i

[@kirannaik4417]

total = total + abs(c[i]) ; I think you had found the mistake..

[@VishalEdu03]

.c[s1.charAt(i) - 'a '] ++ ..anyone can explain using for loop ...

[@MohdAshraf-nw9bz]

HashMap hm= new HashMap(); for(int i=0; i
