A file named mystery. txt contains multiple lines, each line having either the word UP or DOWN or a pair of numbers as shown in the example below. Example file: UP -218 185 DOWN 120 89 210 125 UP UP and DOWN are instructions for a turtle to lift up or put down its tail. The pairs of numbers are some xy coordinates. Write a program that reads the file mystery. txt and uses the turtle to draw the picture described by the commands and the set of points. Like on the previous questions, your program should analyze the points and correctly scale the window using setworldcoordinates so that that the entire mystery figure is seen.

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?
