Begin16. Find the distance between two points with given coordinates \(x_1\) and \(x_2\) on the numerical axis: \(|x_2 - x_1|\).

**Solution in Python 3:**

import random

x1 = random.randrange(-10,10)

x2 = random.randrange(-10,10)

print("x1: ", x1)

print("x2: ", x2)

print("Distance: ", abs(x2-x1))

**Solution in C++:**

#include <iostream>

#include <cmath>

using namespace std;

int main(){

double x1, x2, d;

cout << "Enter the coordinate of x1: ";

cin >> x1;

cout << "Enter the coordinate of x2: ";

cin >> x2;

d = abs(x1-x2);

cout << "Distance: " << d;

return 0;
