Tags: refresh Principle Ultraviolet A 4683 This question refers to a set with a maximum of 12 elements. Find the nth number that can only be divided by one of the sets and only one number. (N I did this by using the refresh principle. First, we will accumulate the number of elements that can be divisible by each number. Of course, there will be duplicates. If a number is composed of two numbers in a set, it must be an integer multiple of all t

Ultraviolet A 12125-March of the Penguins Question Link Given some ice cubes, each ice cube has some penguins. Each ice cube has a limit on the number of jumps. Each Ice Cube is in a coordinate. Now, every penguin jumps to D, ask all penguins if they can jump to a point. If they can output all the frozen ice cubes, print-1 if there is no solution. Idea: Maximum stream. Split points indicate the limit on the number of ice cubes, and then enumerate the

Ultraviolet A 1486-transportation Question Link A directed graph carries K goods, with some sides, each side having a coefficient A. If there is X goods on the side, you have to pay the money of a X, minimum transportation cost from 1 to n Idea: The cost flow. The maximum capacity of this question side is only 5. Therefore, you can split the edge, one side into a C side, and each line has a capacity of 1, the corresponding cost is a * (I ^ 2-(I-1) ^ 2

Solution: For an ordered sequence, consider the probability that each location is valid. C (2 then kn −1 −x) then A (2k2k) then A (n −1 −xn −1 −x) A (n −1n −1)X is the number of positions at which the distance from the current location is less than or equal to k.

Solution: enumerate the cycle length of k limit n. For example, if the current enumeration is 2, u = 1001,1001001, 1001001001 ..., take d = gcd (n, u), then k = u/d, a = n/d (because n ∗ k = u ∗ a) and ensure that t
