Count total unset bits in all numbers from 1 to n

Counting the total number of unset bits (bits with a value of 0) in all numbers from 1 to n involves counting the number of occurrences of each unset bit position in all the binary representations of the numbers from 1 to n.

To do this, we can iterate over all the bit positions in a number's binary representation, and check if each bit is set or not. If a bit is unset, we increment a counter for that bit position. We repeat this process for all the numbers from 1 to n and sum up the counters for each bit position to get the total count of unset bits.
