Problem (2): Write a program that asks the user to input a vector of integers of arbitrary length. Then, using a for-end loop, the program examines each element of the vector. If the element is positive, its value is doubled. If the element is negative, its value is tripled. The program displays the vector that was entered and the modified vector. Execute the program, and when the program ask the user to input a vector type randi (I-10 20], 1, 19). This creates a 19-element vector with random integers between -10 and 20
