Description

shown to student

This program should take a non-zero integer input (which could be negative) and
outputs the string of digits of the number in reverse order. If the number
is negative you should still output a negative sign first.

Template / Reference solution

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
int n;

// write code that allows the user to enter a non-zero integer
// which could be either (pos. or neg). and then
// outputs the number with digits reversed
// Example 1: 321 outputs: 123
// Example 2: -14539 outputs: -93541
// Output a newline after you output the digits in reverse.

cout << "Enter an integer: " << endl;
cin >> n;

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]

[

{"stdin": "-321"},
{"stdin": "321"}
