精彩書摘
Suppose you have a group of N numbers and would like to determine the thh largest. This is known as the selection problem. Most studencs who have had a programming course or two would have no difficulty writing a program Co solve t.his problem. There are quite a few "obvious" solutions.
One way to solve this problem would be to read the N numbers into an array, sort the array in decreasing order by some simple algorithm such as bubblesort, and then return the elemem in poskion k.
A somewhat better algorithm might be to read the first k elements into an array and sort them (in decreasing order). Next, each remaining element is read one by one. As a new element arrives, it is ignored ifit is smaller than the kth element in the array. Otherwise, it is placed in its correct spot in the array, bumping one element out of the array. When the algPo'ithm ends, the element.in the kth position is ret.urned as the answer.
Both algorit.hms are simple to code, and you are encouraged to do so. The natural questions, then, are which algorithm is better and, more important, is either algorithm good enough? A simulation using a random file of 30 million elements and k = l5,000,000 will show that neither algorithm finishes in a reasonable amount of time; each requiresseveral days of compurer processing to cerminate (albeic eventually with a correct answer).An alternative met.hod, discussed in Chapt.er 7, gives a solution in about a second. Thus,although our proposed algorithms work, they cannot be considered good algorithms,because they are entirely impractical for input sizes that a third algorithm can handle in areasonable amount of rime.
