[BAEKJOON] 5357 Dedupe

문제

Redundancy in this world is pointless. Let’s get rid of all redundancy. For example AAABB is redundant. Why not just use AB? Given a string, remove all consecutive letters that are the same.

중복 제커하면 된다고 함

그러면 뭐 for문을 돌려도 1초 이상이 안되기 때문에 괜찮음.

 

import sys

n = int(sys.stdin.readline())

ps = sys.stdin.readlines()

for p in ps:

    tmp = ''

    p = p.strip()

    for i in p:

        if tmp != i:

            tmp = i

            print(i, end='')

    print()
