The range of l and r is 10^18, so you can’t check every number between them, therefore your code is incorrect. Check this implementation https://ide.codingblocks.com/s/228627

Sir What if I use long long here, Please check the code again


And When I am passing the test case being given there, I am just passing int values, even then it is not giving correct output. Why So, Please tell?

No it simply won’t work for 2 reasons.

  1. The size of d array is b-a+1 which can of the order of 10^18 and that much space is not allowed.
  2. Even if that much space was allowed , you aren’t allowed to run such a big loop in which you check every number from a to b, it would give TLE.
