Advice needed on the approach used,TLE IN OP

#1


Is my approach wrong if not can you please tell me modification to be done in same program
Thank you

#2

also im very confused whether to use seperate array to store op or not thats why i think my base case is wrong

#3

please tell me when should be use seperate op array and whe we should not

#4

see first of alll
try using as much of string as u can
char* is little confusing
use a separate string when update has to be made in between in the string
like adding another character b/w existing elements

here
u can simple swap the value when x is found

#5

but is this recursive approach

#6

i dont see no recursive function call
this code is iterative…
