Please tell me how can i solve this question without using another string

#1

I want to modify the input string to contain the answer

#2

u will have to do it using recursion
like using substr(0,i) + “*”+ substr(i+1);

since overwriting the original string would lead to a problem in computing for further inputs

i mean to say that hello
meh if u replace the 2nd l with ‘*’ then u would loose some part of the input string and lead to a WA
hence either use recursion or go for taking another string
