Write a program that $($a$)$ generates a vector with $20$ random integer elements with integers between $-10$ and $10,(b)$ replaces all the negative integers with random integers between $-10$ and $10,(c)$ repeats $(b)$ until all the elements are positive. The program should also count how many times $(b)$ is repeated before all the elements are positive. When done, the program displays the vector and a statement that states how many iterations were needed for generating the vector.
