Thanks for your support. :)

thank you so much

Thank you so much 😀

So nice of you

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

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

Thanks and welcome

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?

@@nikoo28 Yes.. Thanks

this is in JAVA

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

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