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 stringlong 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 codeint main(){ string str = "GfG"; cout << productAscii(str); return 0;} |
Java

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.
