Can you please help me understand this question.

hi @prerna_gupta31
every number is stored in binary format in the memory. A binary number is made up of the digits 1 or 0. 1 is called a set bit.
So given a number, you have to find the number of set bits in it, ie find the number of 1’s in its binary representation.

For eg: 3 can be written as
0011 in its binary form, so 3 has 2 set bits.
Similarly, 4 can be written as
0100 so 4 has only 1 set bit.

So why are we given 2 numbers?

@prerna_gupta31 you will be given a range. You have to find the number of set bits of ALL the numbers present in that range.
