You work at a computer repair store. A customer brought in a computer that shuts down before it can completely boot. You suspect that the problem is with the power supply. In this lab, your task is to complete the following: Test the power supply. Choose a power supply that has the following connectors: The motherboard main power connector (20 4 pin) The CPU power connector (4 pin) A PCIe video card (6 pin) The customer has expressed interest in a new graphics card that requires its own power connector. Make sure that the power supply you select will support this card. Install a power supply in the computer making the following connections: Connect the motherboard power connector. Connect the CPU power connector. Connect the power connector for the SATA hard drive and the optical drive. Plug the computer in using the existing power cable that is plugged into the wall. Start the computer and boot into Windows. If everything is connected correctly, the computer will work.

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges"what's being bought" are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them"for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s . so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of events"s of length m and s of length n, each possibly containing an event more than once"and decides in time o(m + n) whether s is a subsequence of s.
