In how many minimum number of weighs can you find the heaviest ball ? (Answer provided below) 2. There are 4 divers in a cave. The time they take to traverse the cave one way is A = 10mins, B=5mins, C=2mins and D=1min. There is one canister with Oxygen with two attached masks.

Asked question: Using an already implemented method Rand5() that generates a random integer between the ranges 1-5 uniformly. Using this method, implement a a new method that returns a random integer in the range 1-7 uniformly, i.e. Rand7(). Basically this is Rejection Sampling Algorithm. See http://leetcode.com/2010/11/rejection-sampling.html
