题目大意: 你的任务是分类DNA字符串(只有ACGT四个字符,所有字符串长度相同). 根据逆序数,排序程度从好到差. 第一次用到了“类”,和c++里的结构体有类似之处 一次AC,简单暴力的冒泡排序,要不下次来个并归排序? import java.util.Scanner; public class poj1007 { public static class Data{ String s=""; int num=0; Data(){} } public static void main(
[POJ1007]DNA Sorting 试题描述 One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instance, in the letter sequence ``DAABEC'', this measure is 5, since D is greater than fo
All DNA is composed of a series of nucleotides abbreviated as A, C, G, and T, for example: "ACGAATTCCG". When studying DNA, it is sometimes useful to identify repeated sequences within the DNA. Write a function to find all the 10-letter-long seq

Description One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instance, in the letter sequence ``DAABEC'', this measure is 5, since D is greater than four letters to

java Collection中的排序问题 这里讨论list.set.map的排序,包括按照map的value进行排序. 1)list排序 list排序可以直接采用Collections的sort方法,也可以使用Arrays的sort方法,归根结底Collections就是调用Arrays的sort方法. public static <T> void sort(List<T> list, Comparator<? super T> c) { Object[] a
