Answer 1

def bubblesort(arr):
    n = len(arr)
    for i in range(n-1):
        for j in range(n-1-i):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr

def max_pairwise_distance(X):
    res, size = [], len(X)
    for i in range(size-1):
        for j in range(i+1, size):
            res.append(((X[i][0]-X[j][0])**2 + (X[i][1]-X[j][1])**2)**0.5)
    return bubblesort(res)[-1]

if __name__ == "__main__":
    X = [[3,4], [0,0], [-5,12]]
    print(max_pairwise_distance(X))

    X = [[1,4],[5,8],[9,2],[10,7]]
    print(max_pairwise_distance(X))

输出：
13.0
