2 test cases failed in chewbacca problem

what should i improve in this one

hello @mahfoozhaque91

u should never produce leading zeros.

i.e if 9 is the left most digit then leave it as it is. dont make it 0

i have done that in my code like for a number 9999787 it gives 212 as output

thats the issue.

u are not allowed to change the left most digit if it is 9.
for above input output should be
9000212

ca you look what else can be the mistake

can* .

…

check now->

ok got it . I did not understand the problem properly that if the leading number if 9 should not be replaced. Thanks
