hi @anujsharmabadboy you will be given a number n, you have to make strings of length “n” such that, there are no consecutive 1’s, meaning that 1 cannot occur with another 1, it must be surrounded with 0 on both sides.
for eg for n = 3, the following strings can be formed

000 - valid
001 - valid
010 - valid
011 - not valid
100 - valid
101 - valid
110 - not valid
111 - not valid

As you can see from above, we can form 5 valid strings for n = 3, so we report 5 as the answer
