    import numpy as np

n, m = map(int, input().split())

val = np.array([list(map(int, input().split())) for i in range(n)])

print(np.mean(val, axis=1))
print(np.var(val, axis=0))
print(round(np.std(val), 11))

    import numpy as np

    n, m = map(int, input().split())

    ar = np.array([list(map(int, input().split())) for i in range(n)])

    print(np.mean(ar, axis = 1)) print(np.var(ar, axis = 0)) print(round(np.std(ar), 11)) # 11 significant figures to match the expected result format

    from numpy import mean, std, var

res = [
  list(map(int, input().split(' '))) for
  _ in range(int(input().split(' ')[0]))
]

print(
  mean(res, axis=1),
  var(res, axis=0),
  std(res).round(11),
  sep='\n'
)
