1. Prepare and show message in console.
  - Create variables for person name, time, place and event
  - Event should be entered using prompt
  // tip: var smth = prompt("Please enter value", "Default value");
  - Other variables should be set as you wish
  - Join all values to one sentence and show it in console
	// example: Valera has a meeting today at 17:00 somewhere in Warsaw.


2. Find and show (using alert) distance between 2 points.
  - Create variables for x1, y1, x2, y2, result
  - Coordinates of second point (X2, Y2) should be entered using prompt
  - Other variables should be set as you wish
  - Find distance, set it to result variable
  - Alert the result with description
	// example: The distance between points A(0,1) and B(0,11) is 10.

5. Create “Guess number” game.
  - Create variable for random number (from 0 to 100) and set it using Math.random()
	// tip: Math.random() returns number from 0 to 1, so you have to
  // multiply it by 100 and then convert result to integer.
  - Ask user (with prompt) to guess the number
  - If entered number doesn’t equal to our variable, alert “Our number is higher, try again” or “Our number is lower, try again”. Then ask user to enter number again.
  - If user guessed the number, show message “You are right, the number is [number]”.
