Suppose an OS locates a block Z of a file's data by: reading the block number for block X from the double-indirect pointer in the inode, then reading the block number for block Y from the second block pointer stored in block X, then reading the block number for block Z from the first block pointer stored in block Y The first byte of data in block Z corresponds to byte of the file (numbering bytes starting at 0).

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.

Write and test a python program to find and print the largest number in a set of real (floating point) numbers. the program should first read a single positive integer number from the user, which will be how many numbers to read and search through. after reading in all of the numbers, the largest of the numbers input (not considering the count input) should be printed.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
