line 27: s[0] = temp needs to be moved out of the for loop…
@anon11076894
how it will effect the code
it will be assigned every time but at last s[0] will be equals to temp only.
though after this the code is working but i am not getting the logic behind this
s[0] =temp; should be written after the for loop because… you can not change s[0] before it is assigned into s[1].
You could use a better approach… which is not iterative

R is a function to perform left shift twice(although it should be named as L).
left shift includes adding first letter at the end and removing the first letter from beginning.
you are doing lshift twice and then ur comparing it with original string
but in the given question we have to apply right shift and left shift both and the compare with each other…
i am not getting this…
see if right shift of a string is equal to left shift, then shift it any way twice it should result in the same string
R(S)=L(S)
apply R both sides…
=> R(R(S))=S.
if you apply L both sides…
=> L(L(S))=S.
Hope you’d get it.
