Question

给定以数字0结尾的整数序列。确定所有元素彼此相等的最宽片段的长度。即4,4,4,4,31,31,5,5,5,5,5,5应返回6

这是我在学校给出的一项任务，不知道如何完成。请帮忙......

这是我到目前为止的代码：

seq = []
distance = []
x = int(input())
while x != 0:
    seq.append(x)
    x = int(input())

n = str(seq)

for num in seq:
    distance.append(len(seq[''.join(n).find(str(num))-1:''.join(n).rfind(str(num))+1]))

print(max(distance))

Answer 1

如上所述here您可以使用itertools.groupby来实现此目标：

import itertools
a = [4,4,4,4,31,31,5,5,5,5,5,5]
z = [(x[0], len(list(x[1]))) for x in itertools.groupby(a)]
print max(z, key=lambda x:x[1])[1] #6
