Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a sequence a, initially consisting of n integers.
You want to transform this sequence so that all elements in it are equal (i. e. it contains several occurrences of the same element).
To achieve this, you choose some integer ... | instruction | 0 | 15,280 | 12 | 30,560 |
Tags: greedy, implementation
Correct Solution:
```
from collections import Counter
def main(xs):
xs2 = [xs[0]]
# remove consequtive
for i in range(1, len(xs)):
if xs2[-1] != xs[i]:
xs2.append(xs[i])
counter = Counter(xs2)
for k, v in counter.items():
counter[k] += 1
