Please help me solving this problem I am not getting any idea for this.
Problem ->
Given a number N , consider all whole numbers ≤ N , ie, (0,1,…,N) . Find the sum of the bitwise AND of all consecutive numbers.
For example, the bitwise AND of 5= 101 and 7= 111
(5&7)=( 101 & 111 )=101 =5
Since this sum can very large, print the final answer modulo 109+7
(Note: Be careful of overflows while dealing with large numbers.)
