Problem:
 Score : 100 points    Problem Statement Given is an integer r .  How many times is the area of a circle of radius r larger than the area of a circle of radius 1 ?  It can be proved that the answer is always an integer under the constraints given.      Constraints  1 \leq r \leq 100  All values in input are integers.         Input Input is given from Standard Input in the following format:  r       Output Print the area of a circle of radius r , divided by the area of a circle of radius 1 , as an integer.        Sample Input 1 2      Sample Output 1 4  The area of a circle of radius 2 is 4 times larger than the area of a circle of radius 1 .  Note that output must be an integer - for example, 4.0 will not be accepted.       Sample Input 2 100      Sample Output 2 10000
