An easy Problem

问题描述 :

We define eA as following:
Draw
Where A is a n×n symmetric matrix with real elements, I is an identity matrix.
Give you matrix A, your task is to calculate eA.
输入:

There are several test cases;
Each test case begin with a line contains an integer n (1≤n≤100), the following n lines contain n×n symmetric matrix A. The rang of elements of A is (-100,100);
n=0 is the end of input and need not to proceed.
输出:
