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.
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);
}
