USACO USACO 2023 DECEMBER CONTEST SILVER(银级) 第一题 题目解析: 有q对(x,y)的输入,每对表示前1~x个数右边第一个比它们大的数必须在下标为y的位置,这 句话还有一个隐藏含义就是第x+1到第y-1个数必须比前1~x个数的最大值要小,即第y个数 比前y-1个数都要大(代码中称为前缀最大值)。用一个...

Farmer John needs to pickNN(1≤N≤2⋅1051≤N≤2⋅105) locations (not necessarily integers) for his cows to be located. These must be distinct from those already occupied by the cows of Farmer Nhoj, but it is possible for Farmer John to place his cows at the same locations as grass...
首先我们看看字符串的性质: 可交换: CW->WOOC->WC(任何字符串都满足) 表示结果和顺序无关 比如COCWOCWOWWO可以转化为C*3,W*4,O*4,这样的情况下可以直接消掉一大堆(变成c*0/1,O*0/1,W*0/1)这样共8种情况,直接枚举发现只有C、OW满足要求,所以只需要c、o、w三个前缀和,在寻问时看区间里的c、o、...
