Tomorrow is Jim's first day as a teacher in a primary school. He's quite nervous about his new job, and in order to relax he decides to write a simple program, because nothing calms as much as coding.

Since Jim is going to tell the kids about rectangles, he wants to implement a function that will calculate the area of rectangle of the given height and width and show how the result is obtained. Help Jim to gain his confidence and implement the function he needs.

Example

For height = 7 and width = 4, the output should be
solution(height, width) = "7 x 4 = 28".

The area of the rectangle of size 7 × 4 is calculated as 7 * 4 and is equal to 28.

Input/Output

• [execution time limit] 4 seconds (py3)

• [input] integer height

  The height of the rectangle.

  Guaranteed constraints:
  1 ≤ height ≤ 20.

• [input] integer width

  The width of the rectangle.

  Guaranteed constraints:
  1 ≤ width ≤ 20.

• [output] string

  A string containing the area of the given rectangle and how it was obtained in the format "*height* x *width* = *area*"

Solution

class Rectangle(object):
    def __init__(self, height, width):
        self.height = height
        self.width = width

    def __str__(self):
        return '{} x {} = {}'.format(self.height, self.width, self.area)

    def __init__(self, height, width):
        self.height = height
        self.width = width
        self.area = self.height * self.width


def solution(height, width):
    return str(Rectangle(height, width))
