9. Write a program that asks the user to input a vector of integers of arbitrary length. Then, using a for-end loop the program eliminates all the negative elements. The program displays the vector that was entered and the modified vector, and a message that says how many elements were eliminated.

Execute the program and when the program ask the user to input a vector type randi([-15 20],1,25). This creates a 25-element vector with random integers between –15 and 20.
