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.
代码
public String reverseWords(
String s) {
String[] strings = s.
split(
" ");
StringBuilder stringBuilder =
new StringBuilder();
StringBuffer stringBuffer;
for (
int i =
0; i < strings.length; i++) {
stringBuffer =
new StringBuffer(strings[i]);
stringBuilder.append(stringBuffer.reverse().toString() +
" ");
}
return stringBuilder.toString().substring(
0, stringBuilder.length() -
1);
}
