Suppose a binomial heap BH is devised by merging two binomial heaps each with n=2kl keys. a) How many nodes, in terms of n, does BH contain? b) What binomial trees is BH composed of? c) In terms of n, how many binomial trees is BH exactly composed of? d) How many keys are there, in terms of n, in the most crowded depth level of the largest binomial tree
