Write sort.c program, it will be run from the command line as follows: $ ./sort -s 3 -i numbers.txt -o sorted.txt $ Algorithm: Merge sort, #integers: 1024, elapsed time: 0s 333ms sort: name of your program (executable file name)

-s 3: sorting algorithm to use (see below) -i numbers.txt: input text file, to be sorted by the program -o sorted.txt:output text file, sorted numbers are saved to this file Sorting algorithms : 0: Bubble sort 1: Insertion sort 2: Selection sort 3: Merge sort 4: Heapsort 5: Quicksort You should implement these sorting algorithms in your code; you are not allowed to use the sorting algorithms in any library.
