Problem
NASA wants to link n stations spread over the country using communication channels. Each pair of stations has a different bandwidth available, which is known a priori. NASA wants to select n - 1 channels (the minimum possible) in such a way that all the stations are linked by the channels and the total bandwidth (defined as the sum of the individual bandwidths of the channels) is maximum. Give an efficient algorithm for this problem and determine its worst-case time complexity. Consider the weighted graph G = (V,E), where V is the set of stations and E is the set of channels between the stations. Define the weight w(e) of an edge e in E as the bandwidth of the corresponding channel.

A 300-W cylindrical resistance heater is 0.75 m long and 0.5 cm in diameter. The resistance wire is placed horizontally in a fluid at 20° C.
Distinguish between syntax and semantics. Distinguish between a program that the CPU can execute directly and a program that must be translated.
Determine the IT resources that you would employ to automate the process (i.e., electronic documents instead of paper documents).
A processor executes 1000K instructions per second. The bus system allows a bandwidth of 5 MB per second. Assume that each installation requires on average.
When creating a for loop, which statement will correctly initialize more than one variable? When you declare a variable of a basic, primitive type, such as int x = 10;, the memory address where x is located holds the _______.
