Write a recurrence representing the runtime of this private function. The public method is provided for context. Usually it's more clear what the parameters for the recurrence are, but this method has many parameters, and the main input data doesn't decrease in size on each recursive call. If you take a look at the base case and recursive call inputs, you'll see that binary search recursively narrows down the remaining region to search in rather than decreasing the size of the input. You might find it difficult to write the recurrence in terms of low and high directly. Instead, you should write the recurrence in terms of a single parameter: the size of the remaining region to search through-call this m. Then, ask yourself how m decreases with each call, and pass that forward in your recurrence Here's some (modified) code for binary search -a standard example for code that runs in log(n) time worst case! Implementing binary search (recursively and/or iteratively) is a common interview question! 7 public static void funBinarySearch(intI] data, int target) funBinarySearch data, 0, data. length 1, target); 10 12 The first call to this private helper method should search through the entire 13 array, since 0 to data. length 1 is the full range of remaining values to 14 search through. The recursive calls will decrease the size of the range being 15 searched by changing 'low' and high' 16/ 17 private static void funBinarySearch(int] data, int low, int high, int target) 18 if (low > high) { System. out. printin"Done." else ( 20 21 int midlow high) 2; if (data[mid] target) 23 24 25 26 27 system. out, println("Found index " mid +"!"); 1t at + if (data[mid]target) ( funBinarySearch data, mid + 1, high, target); else // data[mid]target funBinarySearch (data, low, mid 1, target); 29 30 31

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?

How is a wan different than a lan? both connect computers, but only wan users don’t need the same operating system. both are peer-to-peer networks, but only a wan requires networking hardware. both network computers, but only a wan can cover larger geographical ranges. both connect computers to the internet, but only wan connects to the cloud.
