@vsinghal277 i don’t get why you are taking two inputs n1 and n2 for each test case .just take a number input and run your logic. check here i have updated your code a little bit (https://ide.codingblocks.com/s/196755)

@vsinghal277 sorry my bad.
for this problem you are just using brute force hence will give you TLE.there comes many optimzed techniques to calculate set bit from 1 to n,here i am using one of those technique and 2’s complementary to handle negative numbers.check my code you will understand (https://ide.codingblocks.com/s/197021)
