[抄题]: 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-lo…
所有DNA由一系列缩写为A,C,G和 T 的核苷酸组成,例如:“ACGAATTCCG”.在研究DNA时,识别DNA中的重复序列有时非常有用.编写一个函数来查找DNA分子中所有出现超多一次的10个字母长的序列(子串). 详见:https://leetcode.com/problems/repeated-dna-sequences/description/ Java实现: class Solution { public List<String> findRepeatedDnaSequences(S…
所有 DNA 由一系列缩写为 A,C,G 和 T 的核苷酸组成,例如:"ACGAATTCCG".在研究 DNA 时,识别 DNA 中的重复序列有时会对研究非常有帮助. 编写一个函数来查找 DNA 分子中所有出现超多(过)一次的10个字母长的序列(子串). 示例: 输入: s = "AAAAACCCCCAAAAACCCCCCAAAAAGGGTTT" 输出: ["AAAAACCCCC", "CCCCCAAAAA"] 需要注意长度只…
很重要的一道题 题型适合在面试的时候考 位操作和哈希表结合 public List<String> findRepeatedDnaSequences(String s) { /* 寻找出现过一次以上的十个字母长的子串 最简单的想法是把每个长度为10的子串存到hashtable中,但是这肯定不符合出题人的意思,要考察位操作 看了答案,使用位操作,第一次做bit manipulation的题 由于A\C\G\T的ASCII码,后三位各不相同,所以我们只要考虑字符的后三位就行 用一个int类型来代表…
