Count total set bits in all numbers from 1 to n
Counting total set bits in all numbers from 1 to n means finding the total number of 1's that appear in the binary representation of all the numbers from 1 to n. For example, the binary representation of numbers from 1 to 5 are:
1  0001 (1 set bit) 2  0010 (1 set bit) 3  0011 (2 set bits) 4  0100 (1 set bit) 5  0101 (2 set bits)
Therefore, the total number of set bits from 1 to 5 is 1+1+2+1+2 = 7.
In simple words, counting total set bits in all numbers from 1 to n involves adding up the number of 1's in the binary representation of all the numbers between 1 and n, inclusive.
