Reverse individual words

Given string str, we need to print the reverse of individual words.

Examples:

Input : Hello World

Output : olleH dlroW

Input : Geeks for Geeks

Output : skeeG rof skeeG

Method 1 (Simple): Generate all words separated by space. One by one reverse word and print them separated by space.


Method 2 (Space Efficient): We use a stack to push all words before space. As soon as we encounter a space, we empty the stack.

Implementation:

// 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();
    }

Way 3: Using StringBuffer Class.

Approach:

  1. O(n) First, convert the string object into a StringBuffer object.
  2. By using the reverse method of the StringBuffer class reverse the string.
  3. Now, store the reverse sequence in a String array.
  4. Run a loop that will create a new String by using these reverse words
  5. Finally, return the new string.

Implementation:


C++ 

#include <algorithm>
#include <iostream>
#include <sstream>
#include <string>

std::string makeReverse(std::string str)
{
    std::reverse(str.begin(), str.end());
    std::istringstream iss(str);
    std::string word;
    std::string reverse;
    while (iss >> word) {
        reverse = word + " " + reverse;
    }
    return reverse;
}

int main()
{
    std::string str = "Geeks for Geeks";
    std::cout << makeReverse(str) << std::endl;
    return 0;

        StringBuffer reverse = new StringBuffer();
        for (int i = rev.length - 1; i >= 0; i--) {
            reverse.append(rev[i]).append(" ");
        }
        return reverse.toString();
    }

Way 4 :

Approach: To store the reversed string instead of just printing

Steps:

  1. Create an empty stack to hold characters from the input string. Create two empty strings: 'rev' (for the reversed string) and 'temp' (for temporary storage).
  2. Iterate through each character in the input string.
  3. If the current character is a letter (an alphabet character) Add it to the 'temp' string to form a word .
  4. If the current character is a space Append a space to the 'rev' string to separate words. Append the content of 'temp' (a word) to 'rev'. Clear 'temp' to prepare for the next word.
  5. After processing all characters. If 'temp' is not empty then add the content of 'temp' to the beginning of the 'rev' string.
  6. Finally, return the 'rev' string.

C++ 

#include <iostream>
