评测机坑爹

评测机坑爹啊...

------------第一次-------------
测试数据 #0: Accepted, time = 0 ms, mem = 2720 KiB, score = 10
测试数据 #1: Accepted, time = 0 ms, mem = 2720 KiB, score = 10
测试数据 #2: Accepted, time = 0 ms, mem = 2716 KiB, score = 10
测试数据 #3: Accepted, time = 0 ms, mem = 2756 KiB, score = 10
测试数据 #4: Accepted, time = 0 ms, mem = 2816 KiB, score = 10
测试数据 #5: Accepted, time = 15 ms, mem = 2812 KiB, score = 10
测试数据 #6: Accepted, time = 171 ms, mem = 5828 KiB, score = 10
测试数据 #7: Accepted, time = 561 ms, mem = 10216 KiB, score = 10
测试数据 #8: Accepted, time = 967 ms, mem = 15220 KiB, score = 10
测试数据 #9: TimeLimitExceeded, time = 1014 ms, mem = 15208 KiB, score = 0
------------第二次-------------
测试数据 #0: Accepted, time = 0 ms, mem = 2720 KiB, score = 10
测试数据 #1: Accepted, time = 0 ms, mem = 2716 KiB, score = 10
测试数据 #2: Accepted, time = 0 ms, mem = 2716 KiB, score = 10
测试数据 #3: Accepted, time = 0 ms, mem = 2748 KiB, score = 10
测试数据 #4: Accepted, time = 15 ms, mem = 2816 KiB, score = 10
测试数据 #5: Accepted, time = 15 ms, mem = 2812 KiB, score = 10
测试数据 #6: Accepted, time = 249 ms, mem = 5828 KiB, score = 10
测试数据 #7: Accepted, time = 592 ms, mem = 10220 KiB, score = 10
测试数据 #8: TimeLimitExceeded, time = 1014 ms, mem = 15212 KiB, score = 0
测试数据 #9: Accepted, time = 967 ms, mem = 15216 KiB, score = 10
------------第三次-------------
测试数据 #0: Accepted, time = 0 ms, mem = 2596 KiB, score = 10
测试数据 #1: Accepted, time = 0 ms, mem = 2596 KiB, score = 10
测试数据 #2: Accepted, time = 0 ms, mem = 2596 KiB, score = 10
测试数据 #3: Accepted, time = 0 ms, mem = 2628 KiB, score = 10
测试数据 #4: Accepted, time = 15 ms, mem = 2692 KiB, score = 10
测试数据 #5: Accepted, time = 0 ms, mem = 2692 KiB, score = 10
测试数据 #6: Accepted, time = 109 ms, mem = 5708 KiB, score = 10
测试数据 #7: Accepted, time = 265 ms, mem = 10100 KiB, score = 10
测试数据 #8: Accepted, time = 406 ms, mem = 15092 KiB, score = 10
测试数据 #9: Accepted, time = 312 ms, mem = 15092 KiB, score = 10

同样的程序,三次都是 VijosEx,为什么会这么大差别?难道是因为多线程评测而造成资源分配不均?随机误差大于500ms也太那个了吧...
顺便吐槽 long long 的效率是 int 效率的 50% 以下,慎用慎用。

    评测机是32位的。

    vijosex一个名字其实有两台机器,所以可能结果不一样。

    还有就是,评测机刚打开,可能还需要“预热”一下什么的。
