reverse word in string

One Line
public class Solution 
{
    public string ReverseWords(string s) 
      => string.Join(" ",s.Trim().Split(' ').Where(x=>x.Length>0).Reverse());
}

Another Approaches

public class Solution 
{
    public string ReverseWords(string s) 
    {
        var stack = new Stack<string>();
        int i=0 ,j=0;
        while(j <= s.Length)
        {
            if( j == s.Length || s[j] == ' ' )
            {
                var sub = s.Substring(i,j-i);
                if(j-i >= 0 && sub.Length > 0) stack.Push(sub); 
                i=++j;
            }
            else j++;
        }
        return string.Join(" ",stack);
    }
}

Given a string, reverse each word in the sentence

function wordsReverser(string){
return string.split("").reverse().join("").split(" ").reverse().join(" ")  
}

console.log(wordsReverser('New string, same results.'));

reverse every word of given sring

// C++ program to reverse individual words in a given
// string using STL list
#include <bits/stdc++.h>
using namespace std;
 
// reverses individual words of a string
void reverseWords(string str)
{
    stack<char> st;
 
    // Traverse given string and push all characters
    // to stack until we see a space.
    for (int i = 0; i < str.length(); ++i) {
        if (str[i] != ' ')
            st.push(str[i]);
 
        // When we see a space, we print contents
        // of stack.
        else {
            while (st.empty() == false) {
                cout << st.top();
                st.pop();
            }
            cout << " ";
        }
    }
 
    // Since there may not be space after
    // last word.
    while (st.empty() == false) {
        cout << st.top();
        st.pop();
    }
}
 
// Driver program to test function
int main()
{
    string str = "Geeks for Geeks";
    reverseWords(str);
    return 0;
}
