Create a program that writes to a file named NumberList.txt; it should use a loop to write the numbers 1 through 100 to the file, each in a separate line, then closes the file. Snap shots of code and output.  

2) Create a program that reads numbers from the NumberList.txt file (the one you created above), reads allthe numbers and displays them to the screen. The program should also add all the numbers in the fileand display their total. Snap shots of code and output.

3) Create a program that opens a directory, reads all the sequence files in that directory and prints out theirsequences into another file (not the console or screen) called Output.txt. The sequences should endwith a || on a separate line. So for example if your directory has two sequence files and Seq1.txt contains this sequence: GAAACCAA And seq2.txt has this sequence: GCCCATTTT
