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.
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.
For each test case, output n lines contain matrix eA , The value of elements of matrix eA must be accurate up to two decimal places. You may assume the range of elements of eA is (-10000,10000).
