n individuals are divided into m-groups to find the minimum number of people in the group.Everyone must match only one group, but a group can match many people and therefore belong to multiple matches.We set a limit that represents the maximum number of people each group can hold. When DFS (U) looks for a match for u, if a group of VV numbers is less than limit, you can match the U and VV, and VV already matches the number of people +1. Otherwise, when the number of people has reached limit, we

following two nodes, then we can combine these three into a single point, the number of scenarios is dp[v1]*dp[v2]* (C (Size (v1) +size (v2,size (v1))); This equation can be understood as: Dp[v1] is the number of V1 of the node, the same as the dp[v2]; The current total number is size[v1]+size[v2]+1;1 for the root node of the above two points, so that the merged nodes are taken SIZE[V1] Put all the points below the V1 then the rest will be put v2 so the legal number is dp[v1]*dp[v2]* (C (Size (

represent a negative number, we place the sign bit again, but this time we also reverse all the value bits (Turn 1 to 0, and vice versa). Now for negative three, we set the sign bit, but let the value bits be empty, give 1 (representing the sign bit), 100 (indicating the value). When we add two numbers, we need a ' round rounding carry ' device, which skips the sign bit and adds the value bit.Note the observations in our add-3 plus +2,-3 plus -1,-3 plus +4, this is how it works (the following p

-point number is represented by the above rule, that is, the calculated value of the exponent e minus 127 (or 1023), the real value, and then the effective digit m plus the first digit of 1. (2) e is all 0. At this point, the index e of the float is equal to 1-127 (or 1-1023), and the effective number m is no longer added to the first bit of 1, but the decimal point is reverted to 0.xxxxxx. This is done to represent ±0, and very small numbers close to 0. (3) e is all 1. At this point, if the

So we turn all the problems into the position of the first 1 in the 0011 pattern sequence. Of course, the actual problem, it is also possible to find the 1100 pattern sequence of the last 1 position.
