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.
class Solution {
public String reverseWords(String s) {
StringBuffer sb=new StringBuffer(s);
StringBuffer newSb=new StringBuffer();
String [] strs=sb.reverse().toString().split(" +");
for(int i=strs.length-1;i>=0;i--){
newSb.append(strs[i]+" ");
}
return newSb.toString().trim();
}
}
