Describe an efficient greedy algorithm that, given a set {x1, x2, ..., xn, } of points on the real line, determines the smallest set of unit-length closed intervals that contains all of the given points. Prove that your algorithm is correct.
a. Briefly describe a greedy algorithm for the unit length interval problem.
b. State and prove a "swapping lemma" for your greedy algorithm.
c. Write a proof that uses your swapping lemma to show that your greedy algorithm does indeed produce a set of intervals that contain all of the points {x1, x2,...,xn} with the fewest number of intervals.

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits. now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order. finally, output thedigits in thearray. use at least two functions to organize your program.
