P.S.- i sometimes stuck in such situations in which my code compiles successfully but it doesn’t show any output. I recheck my code but there is no error. So why is that?

#2

@SATVIK it is stuck in infinite loop. In popcount function.

#3

@SATVIK For even cases a is not reduced.

#4

@SATVI Do a few things before you proceed.
1.Include bits/stdc++.h into your program.
2. Use builtin_popcountll(n) fo counting no of ones.
3. Check your else part in main function. You are reducing your ans there.
