You are given an h×w matrix A consisting of integers between 0 and 26. The element at the i-th row from the top and j-th column from the left is Ai,j.
Let s1,s2,...,sh be h strings of length w that satisfy the following.
The j-th character of si is a period (.) if Ai,j=0, and the Ai,j-th uppercase English letter otherwise (for instance, the 4-th letter is D).
Print s1,s2,...,sh in order.
The first line contains two integers h and w — the width and the height of the matrix A.The next h lines contains the description of the matrix A.
Print h lines. The i-th line should contain si.
