This happened with me as well.

It is happening because of n=1.

Just a separate if statement for n=1 needs to be added.

@akshay29

The order of those if statements in your code is wrong, b[j-1] has to be given preference because it can’t be added to a[j+1].

Therefore if statements having b[j-1] should be placed above others, and a few permutations can be tried :wink:

I just changed the order of if statements, in your code and got AC.

@palashshah

Again the order of if and else if statements is wrong.
