- Find the highest power of $2$ that is lesser than or equal to the given number. Let this number be $x$.
210210
- Calculate the number of set bits from $1$ to $2^x - 1$ by using the formua $x \cdot 2^{x-1}$.

- Count the no. of set bits in the most significant bit from $2^x$ to $n$ and add it.
215-
- Subtract $2^x$ from $n$ and Recurse with the algorithm using the new $n$.

- Subtract $2^x$ from $n$ and repeat the above steps using the new $n$.
