• Visited Japan Innovation Campus
  • https://jp-innovation-campus.org/
  • The co-working space is free for Japanese entrepreneur. Of course I'm not an entrepreneur, but I could drop in today.
  • It was fun working from the place. The atmosphere reminded me of old school days.
  • I don't get why people do networking. Meaningful networks consist of colleagues or close friends; exchanging cards is meaningless. I understand that talking to people with unique experience is interesting though.

Retry: 1993C. Light Switches

I could not solve this problem during the contest, but after some struggle, I managed to pass the tests.

• Each room repeats the statuses (on and off) every 2 * k minutes.
• If there is a timing all the lights are turned on, it is amax <= t <= amax + k.
  • t < amax: the last room's light are off.
  • t > amax + 2k: repeating the same pattern, and they are not the earliest moment.
• Consider the time the last chip is installed as a base.
• Move all the switch cycle closest to the base
• Return the earliest intersection

from collections import defaultdict


for _ in range(int(input())):
    n, k = map(int, input().split())
    a: list[int] = list(map(int, input().split()))

    amax: int = max(a)
    amod: list[int] = [x + (amax - x) // (2 * k) * (2 * k) for x in a]
    amod = [x + 2 * k if amax - x > k else x for x in amod]
    amodmax = max(amod)
    amodmin = min(amod)
    if amodmax - amodmin < k:
        print(amodmax)
    else:
        print(-1)
