Area of Square
Time Limit: 1 sec
A Square is a flat shape with 4 equal sides and every angle is a right angle (90°)
Characteristic of Square
1. All sides are equal in length
2. Each internal angle is 90°
3. Opposite sides are parallel
The Area of square is the side length(a) squared.
Area = a2 = a x a
Write a program that read an integer number which is the side length (a) of Square, your task is to find the area of the Square.
Input file contain a series of line, each line contains only one integer numbers a , which is the side length of square (0<a<=1000). Input is terminated by EOF.
For each line of input, output will show the one integer number which is the area of the square in a separate line.
