There is an image with a height of H pixels and a width of W pixels. Each of the pixels is represented by either `.` or `*`. The character representing the pixel at the i-th row from the top and the j-th column from the left, is denoted by C_{i,j}.  Extend this image vertically so that its height is doubled. That is, print a image with a height of 2H pixels and a width of W pixels where the pixel at the i-th row and j-th column is equal to C_{(i+1)/2,j} (the result of division is rounded down).
c=input()
if c in ['a', 'e', 'i', 'o', 'u']:
    print ('vowel')
else:
    print('consonant')

H, W = [int(n) for n in input().split()]
for h in range(H):
    C = input()
    print (C+'\n'+C)
