1. You are given an array of n numbers.
2. You have to find the sum of bit differences in all pairs that can be formed from n numbers.
3. Bit difference of two numbers is defined as the count of different bits at same positions in binary representations of two numbers.

4:50 the last x 2 is actually x 2!, because it counts all permutations of the 2 elements in the pair since order does not matter.
super explanation....Thanks !

sir ek cheez clear nhi ho rhi ...hume countOn aur countOff ko long mei lena kyu pd rha h.....countOn ki value humesha arr.length se km ya equal honi chaiye ...or arr.length to integerRange mei hi rhega humesha

Jab multiplication CPU register level pe perform hoti hai tab multiplication result temporarily operand me store kia jata hai. For example: A = B * C; when B will be multiplied with C then the result will be temporarily held in B then that temporary value will be copied in A and the original value will be set in B. So, if B * C exceeds Integer Range and could not be stored in B, the system gives an error. So, its better to take LONG and then typecast the result to INT after modulo 10^9 + 7 if the return type is INT. Hope this helps.
Great Explaination sir..

use modulo there and store ans in long long int, it will work fine.
i think considering ordered pairs is wrong
thank u sir orz
