how many mice have

Everyone should have heard of this old topic: there are 1000 identical bottles, of which 999 are ordinary water and one bottle is poison. Any creature that drinks poison will die in a week. Now, you only have 10 mice and a week, how do you check out which bottle is poisonous?The answer to this question is also classic: numbering the bottles from 0 to 999, then converting them all to 10-bit binary numbers. Get the first rat to drink. 1 to 1000 all bina

Really, I dreamed of it last night. A mouse ran to a friend's house, and my friend refused to kill it and said it was cute. The result quickly became a problem.Then I woke up, hey! I don't know what preference this dream is. I haven't found Zhou gongjie on the Internet for a long time.However, I woke up after my dream was completed. I thought of a program question, which I had come up: There were 30 mice in one household, which were so rampant tha

The questions are as follows: There are 1000 Identical bottles in the lab, but one of them is toxic. You can use lab mice to test which bottle is a poison. If the mouse drinks the poison, it will die in a week. The potion in other bottles has no side effects. Could you tell me the minimum number of mice that can be used to find out which bottle is poison within a week:A.9B. 10C. 32D. 999.E. None of the abo

Mice and Holes CodeForces, holescodeforces Mice and Holes CodeForces-797F There are n rats and m holes on a digital axis. The coordinates of the mouse are x [1],..., x [n], the coordinate of the hole is p [1],..., p [m], each hole can accommodate c [1],..., c [m]: Ask the minimum value of the sum of the distances that every mouse runs after hiding in the hole.

Codeforces Round #105 D. Bag of mice probability dp, Http://codeforces.com/contest/148/problem/D The question is that dragon and Princess take turns pumping mice from the bag, W white teachers in the bag, and D black teachers. The Princess smokes first, and the first pulls the white mouse to win, the dragon will randomly run out of a mouse each time it is pumped. Give W and D for you to find the probability

Probability DPThe 9th question in Kuangbin summaryAh ... The data given by the topic are only the number of rats and black rat, so we can only do this (GAO) (P).Obviously can use the number of two kinds of mice as state = =My WA Approach:Make F[i][j] said from (w,b) take the mouse one until (i,j) "This time round process take" two people have been dead heat probability, it is obvious (I,J) This state win probability is I/(I+J), then the probability of

DP [x] [Y]: Now there are X white mice, y black mice, and the probability that the princess will win. So: Assume that the princess gets the white mouse directly. The probability is X/(x + y), and the princess wins. Assuming that the princess gets the black mouse, the probability is Y/(x + y), then the princess assumes that to win, the dragon must get the black mouse, the probability is (Y-1)/(x + Y-1 ); The

Probability, $DP $.$DP [i][j][0]$ says there is still $i$ a white cat, $j $ A black cat, the probability of the princess reaching the target State in case of a shot.$DP [i][j][1]$ says there is still $i$ a white cat, $j $ A black cat, the probability of reaching the target State in case of a dragon shot.At first $dp[i][0][0]$ are $1$, the answer is $dp[w][b][0]$. The recursive type is easy to write:$DP [i][j][0]=i/(I+J) +j/(i+j) *dp[i][j-1][1]$$DP [i][j][1]=j/(I+J) *i/(i+j-1) *dp[i-1][j-1][0]+j*

A mouse liked cheese, but it was put in N rooms, and there was a cat guard in these rooms. Now it is ready to trade with the cats. It has m-pound cat food and wants to use this m-pound cat food for cheese. In every room guarded by a cat, there is a cheese J [I] pound, and the cat needs f [I] pound food. If the teacher gives the cat f [I] * a % of cat food, then it can get J [I] * A % cheese. Now we know the demand for cat food and the number of cheese in each room for each cat. How can a mouse g
