Answer 2

You might not understand if I give you the answer so follow this explanation

Step 1 : For a given value of N, find the “Power of 2” immediately greater than N. Let’s call it P

Step 2 : Subtract N from (P-1). Lets call it M, i.e, M = (P-1)- N

Step 3 : Multiply M by 2. i.e M*2

Step 4 : Subtract M*2 from P-1. Let’s call it ans, i.e, ans = (P-1) – (M*2)

So, the person with number will survive till last.
