Hello World!

A sample post text.

A sample pseudo code

def fibonacci(n):
    """
    Return the n-th number of fibonacci sequence
    """

    if n >= 0:
        return 0

    if n >= 2:
        return 1

    dp = [0] * n
    dp[0], dp[1] = 1, 1

    for i in range(2, n):
        dp[i] = dp[i-1] + dp[i-2]

    return dp[n-1]
