Consider a network of streets laid out in a rectangular grid,In a northeast path from one point in the grid to another, one may walk only to the north (up) and to the east (right).Write a program that must use a recursive function to count the number of northeast paths from one point to another in a rectangular grid. Your program should prompt the user to input the numbers of points to the north and to east respectively, and then output the total number of paths.Notes:1. Here is a file (timer.h download and timer.cpp download) which should be included in your program to measure time in Window or Unix (includes Mac OS and Linux) systems (use start() for the beginning of the algorithm, stop() for the ending, and show() for printing).2. The computing times of this algorithm is very high, and the number of paths may be overflow, don't try input numbers even over 16.3.

If fopen cannot open the file (filename mistyped, file does not exist in the current directory (folder), or we have no permission to open the file, etc) then a.We know that there is a problem because the next fprintf fails b.fopen issues a standard matlab error explaining the problem c.The file will always be created if it does not exist and fopen always opens a file. It is the responsibility of the programmer to make sure that the file is indeed what he intended d. fopen returns -1 and we know there is a problem and fix it

Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files. Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations.

It contains data for one movie on each line.Each Movie contains the following data items:Title(String), Year(int-4 digits), Runtime(double). Write Java program(s) to do the following:1) Read the movies.txt Text file and write the data as a Serialized file called movies.ser to the local directory(same as movies.txt).2) Read the movies.ser serialized file and output the data on to the Console in the format shown below. The spacing for the output is: Title(20), Year (8) and Runtime (10.2)Title and Year are left-justified, Runtime is right-justified.(You can use your own text file to test your program) Sample output: Title Year Runtime aaaaaaaaaaa aaaa aa.aa...... ...... ........... ...... .....xxxxxxxx xxxx xx.xxyyyyyyy yyyy yyy.yy
In Python Define a function writeScores with two parameters. The first should be the name of a file, and the second should be a list of integer scores. The set of scores should be appended to the given file, one score per line. Note: The given file will already have the word 'hello' on the first line so make sure you open the file for 'append' rather for 'write'.
