Imprime el último carácter de cada palabra en una string

Dada la string str , la tarea es imprimir el último carácter de cada palabra en la string.

Ejemplos:  

Entrada: str = «Geeks para Geeks» 
Salida: srs

Entrada: str = «aplicaciones informáticas» 
Salida: rs 

Enfoque: agregue un espacio, es decir, «» al final de la string dada, de modo que la última palabra de la string también vaya seguida de un espacio, como todas las demás palabras de la string. Ahora comience a recorrer la string carácter por carácter e imprima cada carácter seguido de un espacio.
A continuación se muestra la implementación del enfoque anterior: 

// CPP implementation of the approach
#include<bits/stdc++.h>
using namespace std;
 
// Function to print the last character
// of each word in the given string
void printLastChar(string str)
{
 
    // Now, last word is also followed by a space
    str = str + " ";
    for (int i = 1; i < str.length(); i++)
    {
 
        // If current character is a space
        if (str[i] == ' ')
 
            // Then previous character must be
            // the last character of some word
            cout << str[i - 1] << " ";
    }
}
 
// Driver code
int main()
{
    string str = "Geeks for Geeks";
    printLastChar(str);
}

    // Function to print the last character

    static void printLastChar(String str)
    {
 
        // Now, last word is also followed by a space
        str = str + " ";
        for (int i = 1; i < str.length(); i++) {
 
            // If current character is a space
            if (str.charAt(i) == ' ')
 
                // Then previous character must be
                // the last character of some word
                System.out.print(str.charAt(i - 1) + " ");
        }
    }
 
    // Driver code
    public static void main(String s[])
    {
        String str = "Geeks for Geeks";
        printLastChar(str);
    }
}

# Function to print the last character
# of each word in the given string
def printLastChar(string):
 
    # Now, last word is also followed by a space
    string = string + " "
    for i in range(len(string)):
 
        # If current character is a space
        if string[i] == ' ':
 
            # Then previous character must be
            # the last character of some word
            print(string[i - 1], end = " ")
 
# Driver code
string = "Geeks for Geeks"
printLastChar(string)
