programming. (Hint: The square root to be used for testing should be rounded up‚ i.e.‚ take the ceiling function) Draw (by hand or using Computer CAD tools‚ such as Visio) a flowchart for the testing algorithm. In this lab‚ we assume that the test integer is smaller than 100‚000‚ (if it is greater than 100‚000‚ your code simply returns to indicate that it is a non-prime number). Include a snapshot of your hand-drawn flowchart or computer generated one and all other prelab requirements in your lab

OLYMPIC TIN HỌC HUFLIT 2014 BÀI 11 (NC) UNION-FIND DISJOINT SETS THEORY In computing‚ a disjoint-set data structure‚ also called a union–find data structure or merge–find set‚ is a data structure that keeps track of a set of elements partitioned into a number of disjoint (nonoverlapping) subsets. It supports two useful operations: o Find: Determine which subset a particular element is in. Find typically returns an item from this set that serves as its "representative"; by comparing the

September 25‚ 2010 Revised June 1‚ 2011 A number of graph coloring problems have their roots in a communication problem known as the channel assignment problem. The channel assignment problem is the problem of assigning channels (non-negative integers) to the stations in an optimal way such that interference is avoided‚ see Hale [4]. The radio coloring of a graph is a special type of channel assignment problem. Here we develop a technique to find an upper bound for radio number of an arbitrary
