I tried to print the permutations but I cant get correct output

#1


I am getting all lengths of strings but I only need fixed length equal to no. of characters in the question. So how can I approach this problem .I am facing a bit diffuculty while solving using recursion.
Can you also share some tips on how to visualise and utilize recursion effectively? I might find it really helpful if u can give some insights

hello @gvspraveen113

u are not using return statement in ur base case.

dry run on small test case (2-3 length string) will give decent idea about code flow.

can you provide any code for reference
