明明想在学校中请一些同学一起做一项问卷调查，为了实验的客观性，他先用计算机生成了N个1到1000之间的随机整数（N≤100），对于其中重复的数字，只保留一个，把其余相同的数去掉，不同的数对应着不同的学生的学号。然后再把这些数从小到大排序，按照排好的顺序去找同学做调查。请你协助明明完成“去重”与“排序”的工作，并对自己的程序进行复杂性分析。-Obviously want to ask some of the students in the school to do a survey to test the objectivity, his first with the computer generated between the N 1-1000 random integer (N ≤ 100), for which duplicate numbers only retained one removed the rest the same number, corresponding to the number of different students learn different number. Then put a few of these small to large, according to the sorted order to find someone to do the investigation. Please help obviously Finish " go heavy"　and " sort"　of work, and the complexity of the analysis carried out their own procedures.
