easy to understand solution in C++ for beginners

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
#include <map>

using namespace std;

int N = 1e4;

int main() {
    vector<char> arr;
    char* str = new char[N];
    cin.getline(str, N);
    int i = 0;
    while (str[i] != '\0') {
        arr.push_back(str[i]);
        i++;
    }
    delete[] str;

    string result;
    vector<string> st = {"Hello,", "World."};
    for (size_t i = 0; i < st.size(); ++i) {
        result += st[i];
        if (i < st.size() - 1) {
            result += " ";
        }
    }
    cout << result << endl;

    map<int, char> myMap;
    for (int i = 0; i < arr.size(); ++i) {
        myMap.insert({i, arr[i]});
    }

    for (auto& entry : myMap) {
        cout << entry.second;
    }
    cout << endl;

    return 0;
}

Read a full line of input from stdin and save it to our dynamically typed variable, input_string.

input_string = input()

Print a string literal saying "Hello, World." to stdout.

print('Hello, World.')

print(input_string)

TODO: Write a line of code here that prints the contents of input_string to stdout.

this is an example of using the golang language, by adding the bufio and os packages so you can see if there are any more sentences after the first sentence

package main import( "fmt" "bufio" "os" )

func main() { //Enter your code here. Read input from STDIN. Print output to STDOUT inputString := bufio.NewScanner(os.Stdin) for inputString.Scan() { fmt.Println("Hello, World.") fmt.Println(inputString.Text()) // Println will add back the final '\n' } if err := inputString.Err(); err != nil { fmt.Fprintln(os.Stderr, "reading standard input:", err) } }

print('Hello, World.') for i in inputString: print(i,end = "")
