Program to find the product of ASCII values of characters in a string

Given a string str. The task is to find the product of ASCII values of characters in the string.

Examples: 

Input : str = "IS"
Output : 6059
73 * 83 = 6059

Input : str = "GfG"
Output : 514182

The idea is to start with iterating through characters of the string and multiply their ASCII values to a variable namely, prod. Hence, return prod after the complete iteration of string.

Note: If the string is large, the program may cause segmentation fault because of the limited size of an int.

Implementation:

C++

// C++ program to find product
// of ASCII value of characters
// in string

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

// Function to find product
// of ASCII value of characters
// in string
long long productAscii(string str)
{
    long long prod = 1;

    // Traverse string to find the product
    for (int i = 0; i < str.length(); i++) {
        prod *= (int)str[i];
    }

    // Return the product
    return prod;
}

// Driver code
int main()
{
    string str = "GfG";

    cout << productAscii(str);

    return 0;
}

Java

// Java program to find product
// of ASCII value of characters
// in string
class GFG
{

// Function to find product
// of ASCII value of characters
// in string
static long productAscii(String str)
{
    long prod = 1;

    // Traverse string to find the product
    for (int i = 0; i < str.length(); i++)
    {
        prod *= str.charAt(i);
    }

    // Return the product
    return prod;
}

// Driver Code
public static void main(String[] args)
{
    String str = "GfG";

    System.out.println(productAscii(str));
}
}

def productAscii(str):

    prod = 1

    # Traverse string to find the product
    for i in range(0, len(str)):
        prod = prod * ord(str[i])

    # Return the product
    return prod

# Driver code

Output

514182

Time Complexity: O(N), where N is the length of string.
Auxiliary Space: O(1), no extra space is required, so it is a constant.
