# number of cases given
n = int(input())
for i in range(n):
    # handle case

# stop at signal value:
x = int(input())
while x != 0:
    x = input()

# multiple data sets (hybrid of above):
n = int(input())
while n != 0:
    for i in range(n):
        #handle case
    n = int(input())

# read whitespace-separated line and parse into list:
data = input().split()

# read whitespace-separated line and parse into list, converting to integers
data = [int(x) for x in input().split()]

# write single integer
print("%d" % x)

# write multiple integers, padded to six characters each
print("%6d %6d" % (x, y))

# write float with two decimal digits
print("%.2f" % x)

# write float with two decimal digits, padded to 8 chars
print("%8.2f" % x)
