    It’s a simple task, but it really strengthens your understanding of string handling in C++. Radhe Exch

    vector<int> parseInts(string str) {
	stringstream ss(str);
    vector<int> out;

    While the stringstream is reading from the stream (string in this case):

    vector<int> parseInts(string str) {
    vector<int> v;
    int n;
    char c;
    stringstream ss(str);
    while(ss) {
        ss >> n >> c;
        v.push_back(n);
    }
    return v;
}

    Very easy intuition

    #include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#include <sstream>
using namespace std;


int main() {
    string s;
    cin >> s;
    stringstream ss(s);
    char ch;
    int a;
    
    while (true) {
        ch = '0';
        ss >> a >> ch;
        cout << a << endl;
        if (ch != ',') {
            break;
        }
    }
    
    return 0;
}
