can anyone tell me what is wrong in my code
I am following the approach given in the editoial
Here’s a test case:
393383587145601330 571238254289132474
The answer should be:
576460752303423487
but your code produces:
576460752303423488
Off by 1 digit.
Spoiler
Line 45
How about changing that to ans += 1LLU << i;?
If you refer to this, you’ll know that pow is simply not enough for dealing with such large numbers.

ok thanks
my solution got accepted after I multiplied 2 repeatedly in for loop rather than using pow function
