Money Transfer Max. score: 100 SeaMoney has a feature to transfer money between users. Let's imagine a simple scenario. N usernames--consisting of lowercase Latin characters-each starts with a balance b. Amongst them, T transactions happened, where user ua transfers x amount of money to ub. If x is larger than the ua's balance when the transaction happens, the transaction is automatically rejected. Output the final balance of each user. Input The first line contains two numbers N and T (1 < N,T < 1000). Each of the next N following lines contain username u; (1< ]u;| < 10) and integer b; (1 < b; < 10°), denoting the balance of user u;. Following that (1

Write a program that simulates a paging system using the aging algorithm. The number of page frames is a parameter. The sequence of page references should be read from a file. For a given input file, plot the number of page faults per 1000 memory references as a function of the number of page frames available. Code Solution: https://github.com/preethikandhalu/C/blob/master/aging.c Task to be done based on the above program: Describe what the code does, explaining how it accomplishes its task of implementing the aging page replacement algorithm. You must create an input file for simulating a sequence of page references. Run the program. (Fix any bugs that it may contain, first). Vary the number of page frames, keeping the sequence of page references constant. What can you infer from the results? Plot the output in an Excel graph. Explain your findings. Adjust your inputs to get meaningful outputs.
Create two Python programs that use NumPy I/O capabilities to write and read data files using numpy.loadtxt() and numpy.savetxt(). A writer program will generate two samplings of y=f(x) over the x range of -2pi..+2pi: y=cos(x) and y=sinc(x), will make a plot of these two samplings, and write out two files containing the samplings. A reader program will load the two files created by the writer, and make a plot of the contents of both files. For this assignment, please turn in these 4 things: Python code for the writer Python code for the reader The 2 data file(s) produced by the writer

Solve the following in C## Run Length Encode Manytimes,certaindatafiletypescanconsistoflarge amounts of repeated data. For instance, images can have large runs of the same color. This can be easily compressed using a technique called run length encoding. With run length encoding, large amounts of repeated data are stored as the repeated data and the number of times to repeat it. CreateaclassRunLengthEncodethatcontainsthemethod encode which takes one argument: a String to be encoded as described below. ThereturnvalueshouldbeaStringwhichhasbeenencoded with the following algorithm: Ifanycharacterisrepeatedmorethan4times,theentire set of repeated characters should be replaced with a slash '/', followed by a 2-digit number which is the length of the set of characters, and the character. For example, "aaaaa" would be encoded as "/05a". Runs of 4 or less characters should not be replaced since performing the encoding would not decrease the length of the string. Notes Letters are…
