Code failing on test case 0

#1

Why this code is failing on only Test Case 0, and all others are passing…?

#2

Two strings a and b of equal length are called equivalent in one of the two cases:

  1. They are equal.
  2. If we split string a into two halves of the same size a1 and a2, and string b into two halves of the same size b1 and b2, then one of the following is correct:
    1. a1 is equivalent to b1, and a2 is equivalent to b2
    2. a1 is equivalent to b2, and a2 is equivalent to b1

to check a1 and b1 are equivalent or not you have to check these conditions again

you have to use recursion for that
i hope you got the point
if not feel free to ask

#3

check for this input
abcd
dcba

they are equivalent

#4

a=“abcd”
b=“dcba”

a1=“ab” a2=“cd”,
b1=“dc” b2=“ba”

now check equivalence of a1 and b2

so now
a=“ab”
b=“ba”

a1=“a” a2=“b”
b1=“b” b2=“a”
hence they are equivalent

Oh okay,i got it now…Thank you for the explanation!
