[LeetCode] 557. Reverse Words in a String III
Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.
Example 1:
Input: "Let's take LeetCode contest" Output: "s'teL ekat edoCteeL tsetnoc"
Note: In the string, each word is separated by single space and there will not be any extra space in the string.
题意,翻转每个字符串中的单词
道理还是翻转字符串就是换了个形式罢了,按空格拆就好
class Solution { private String reverseString(String s) { String str = ""; for (int i = s.length() - 1; i >= 0; i --) str += s.charAt(i); return str; } public String reverseWords(String s) { String str = ""; String temp = ""; for (int i = 0; i < s.length(); i++) { if (s.charAt(i) == ' ') { str += reverseString(temp); str += " "; temp = ""; } else temp += s.charAt(i); } str += reverseString(temp); return str; } }
