如何从列表中获取最不同的字符串

def get_most_different_string(strings):
    min_diff = float('inf')
    most_different_string = ""

    for i in range(len(strings)):
        diff_sum = 0

        for j in range(len(strings)):
            if i != j:
                diff_sum += edit_distance(strings[i], strings[j])

        if diff_sum < min_diff:
            min_diff = diff_sum
            most_different_string = strings[i]

    return most_different_string

def edit_distance(str1, str2):
    m = len(str1)
    n = len(str2)
    dp = [[0] * (n + 1) for _ in range(m + 1)]

    for i in range(m + 1):
        dp[i][0] = i

    for j in range(n + 1):
        dp[0][j] = j

    for i in range(1, m + 1):
        for j in range(1, n + 1):
            if str1[i - 1] == str2[j - 1]:
                dp[i][j] = dp[i - 1][j - 1]
            else:
                dp[i][j] = min(dp[i - 1][j - 1], dp[i][j - 1], dp[i - 1][j]) + 1

    return dp[m][n]

# 示例用法
strings = ["hello", "world", "cloud", "computing"]
most_different = get_most_different_string(strings)
print(most_different)
