[3 points] Let T be a heap storing n keys. Give an efficient algorithm for reporting all the keys in T that are smaller than or equal to a given query key x (which is not necessarily in T). For example, given the heap of below figure and query key x = 7, the algorithm should report 4, 5, 6, 7. Note that the keys do not need to be reported in sorted order. Your algorithm should run in 0(k) time, where k is the number of keys reported. 20 [3 points] Let T be a heap storing n keys.
