Print each word in a sentence with their corresponding average of ASCII values

Given a sentence, the task is to find the average of ASCII values of each word in the sentence and print it with the word.

Examples:

Input: sentence = “Learning a string algorithm”
Output:
Learning – 102
a – 97
string – 110
algorithm – 107

Approach:

1. Take an empty string and start traversing the sentence letter by letter.
2. Add a letter to the string and add its ASCII value to the sum.
3. If there is a space calculate the average by dividing the sum by the length of the string (word)
4. Clear the string so that it can be used for the next word
5. Also, set the sum to zero.

Below is the implementation of the above approach:

C++

// C++ program of the above approach

#include <bits/stdc++.h>
using namespace std;

// Function to calculate the
// average of each word in a sentence
void calculateAverage(string sentence)
{
    // Word initialised to an empty string
    string word = "";

    // Sum of ascii values
    int sum = 0;

    int len = sentence.length();

    for (int i = 0; i < len; ++i) {

        // If character is a space
        if (sentence[i] == ' ') {

            // Calculate the average
            int average = sum / word.length();

            cout << word << " - "
                 << average << endl;

            // Clear the word and
            // set the sum to 0
            word.clear();
            sum = 0;
        }

        else {

            // Add the ascii value to sum and
            // also add the letter to the word
            sum += sentence[i];
            word += sentence[i];
        }
    }

    // Calculate the average of last word
    int average = sum / word.length();

    cout << word << " - " << average;
}

// Driver code
int main()
{

    // Get the sentence
    string sentence
            = "Learning a string algorithm";

    // Calculate the average
    calculateAverage(sentence);

    return 0;
}

Java

// Java program of the above approach
import java.util.*;
public class Solution
{
// Function to calculate the
// average of each word in a sentence
static void calculateAverage(String sentence)
{
    // Word initialised to an empty string
    String word = "";

    // Sum of ascii values
    int sum = 0;

    int len = sentence.length();

    for (int i = 0; i < len; ++i) {

        // If character is a space
        if (sentence.charAt(i) == ' ') {

            // Calculate the average
            int average = sum / word.length();

            System.out.println( word + " - "+ average );

            // Clear the word and
            // set the sum to 0
            word="";
            sum = 0;
        }

        else {

            // Add the ascii value to sum and
            // also add the letter to the word
            sum += sentence.charAt(i);
            word += sentence.charAt(i);
        }
    }

    // Calculate the average of last word
    int average = sum / word.length();

System.out.print( word + " - " + average);
}

// Driver code
public static void main(String[] args)
{

    // Get the sentence
    String sentence
            = "Learning a string algorithm";

    // Calculate the average
    calculateAverage(sentence);
