Given string str, the task is to find the frequency of all digits (0-9) in a string created by concatenating the ASCII values of each character of the given string str.
Example:
Input: str = “GeeksForGeeks”
Output: 7 21 0 0 1 2 0 5 0 0
Explanation: The array of ASCII values of all characters of the given string is {71, 101, 101, 107, 115, 70, 111, 114, 71, 101, 101, 107, 115}. Hence, the frequency of digit 0 in the array is freq[0] = 7. Similarly, freq[1] = 21, freq[2] = 4, freq[3] = 0, and so on.Input: str = “Computer123”
Output: 3 15 1 0 2 2 2 2 0 2
Approach: The given problem is an implementation based problem and can be solved by following the given steps:
- Create a string asc, which stores the ASCII value of each character.
- Traverse the given string str, find the ASCII value of each character and append it into asc using the to string inbuilt function.
- Traverse the string asc and update the frequency of the current digit stored in a frequency array.
- Print the frequency of each digit.
Below is the implementation of the above approach:
C++
// C++ program of the above approach#include <bits/stdc++.h>using namespace std;// Function to find the frequency of// all digits in the array of ASCII// values of all characters of strvoid digitFreq(string str){ // Stores the ASCII string string asc = ""; // Loop to traverse string for (auto x : str) { // Append ASCII value of // current string to asc asc += to_string((int)x); } // Stores frequency of digits int freq[10] = {}; // Loop to traverse asc for (auto x : asc) { freq[x - '0']++; } // Print frequency of each digit for (int i = 0; i < 10; i++) { cout << freq[i] << " "; }}// Driver Codeint main(){ string str; str = "GeeksForGeeks"; digitFreq(str); return 0;} |
