For this assignment you have to write a C program that will utilize the merge sort and binary search algorithm. Problem In this assignment, you have to read a text file (in. txt) that contains a set of point coordinates (x, y). The first line of the file contains the number of points (N) and then each line of the file contains x and y values that are separated by space. The value of x and y are integer. They can be both negative and positive numbers. You have to sort those points in x-axis major order and then write the output into another file (out. txt) in the same format, i. e., each line contains one coordinate point and the value of x and y are space delimited. After writing the sorted points in the file, your program should display "sorted and output written". After that your program should prompt the user for an input coordinate point x and y values and your program should perform binary search to determine whether the point exist in the given list of points. If it is found, it should show "Found at record number ". If not, say not found. Sample Input file in. txt: 6 3 4 6 2 5 2 7 5 2 Sample Input file out. txt: 2 5 2 7 4 6 5 2 6 3 "Sorted and output written" Search input (x y): 2 3 Output: Not found Search input (x y): 4 6 Output: Found at record 3 Requirement: You must use file IO, Merge sort and binary search for your solution.
