Hello @goyalvivek,
According to the problem you are given a sequence, whose each element has prime factors of 2, 3 or 5
So, let’s see what the sequence looks like,
1 2 3 4 5 6 8 9 10 12 15 16 18 20 …

Now the question is you are given t queries and in each query, you are asked to print nth element of the above sequence,
Like 7th element = 8
10th element = 12
