we have two databases of size n containing numbers without repeats. So, in total we have 2n elements. They can be accessed through a query to one database at a time. The query is such that you give it a k and it returns kth smallest entry in that database. we need to find nth smallest entry among all the 2n elements in O(logn) queries. t...
You need to use division and remainder by 10. Consider this example: 163 divided by 10 is 16, remainder 3 16 divided by 10 is 1, remainder 6 1 divided by 10 is 0, remainder 1 You'll notice the remainder is always the last digit of the number that's being divided. How do I do this in C? ...
